Metallised film capacitors for high frequency, high current applications

[{u'author_order': 1, u'affiliation': u'Ind. Capacitors Ltd., Wrexham, UK', u'authorUrl': u'', u'full_name': u'N. Williams', u'id': 37848094100}] IEE Colloquium on Capacitors and Inductors for Power Electronics (Digest No: 1996/054), 1996

Some modern applications such as the resonant inverter, use a large number of passive devices. These devices need to operate at very high frequencies and consequently high currents, albeit at moderate voltage levels. This paper aims to outline the design approach to such an application, showing how traditional assembly methods were abandoned in favour of a more radical approach. It ...

Power capacitors-new developments

Capacitors are used in many applications ranging from traction, reactive power compensation through to furnace duties. To varying degrees many applications require capacitors with the highest available energy densities. Two examples include DC filter capacitors for traction applications where weight and volume of the traction convertor is always limited. Secondly high voltage reactive compensation where as demands on the electricity ...

[{u'author_order': 1, u'affiliation': u'Nottingham Univ., UK', u'authorUrl': u'', u'full_name': u'W.F. Ray', u'id': 37849918100}] IEE Colloquium on Capacitors and Inductors for Power Electronics (Digest No: 1996/054), 1996

Plastic film capacitors have always played an important role in power electronic circuits. In the earlier days of thyristors with forced turn-off, large capacitors of tens or even hundreds of microfarads were used for commutation purposes. Much smaller capacitors are used for snubber networks with transistors and other controlled switching devices, and more recently capacitors play an important role in ...

Interpretation of ratings for electrolytic capacitors

[{u'author_order': 1, u'authorUrl': u'', u'full_name': u'W.F. Ray', u'id': 37849918100}] IEE Colloquium on Capacitors and Inductors for Power Electronics (Digest No: 1996/054), 1996

Electrolytic capacitors do not arouse much analytical interest and yet they represent a significant proportion of the cost of most power electronic systems. It is therefore of benefit to fully utilise their ratings. Ripple current ratings for electrolytic capacitors are usually provided for operation at 85/spl deg/C ambient. A particular capacitor can be operated at higher currents with lower ambient ...

Lim', u'id': 37428191600}, {u'author_order': 2, u'authorUrl': u'', u'full_name': u'A.V. Kordesch', u'id': 37297604400}, {u'author_order': 3, u'authorUrl': u'', u'full_name': u'R.A. Keating', u'id': 37370195000}] 2004 RF and Microwave Conference (IEEE Cat. No.04EX924), 2004

In this work, we compare silicon nitride MIM capacitors to metal finger capacitors and clarify the performance and cost trade-offs. Our measurements show that MIM capacitors are superior to metal finger capacitors in terms of matching and process tolerance, but equivalent metal finger capacitors have higher Q, lower voltage coefficient and lower temperature coefficient.

  • Ultra-Capacitor Energy Storage Devices

    The ultra-capacitor as an emerging energy storage device dedicated to power conversion applications. The ultra-capacitor structure, operation principle and a macro (electrical) model are discussed intensively. Charging and discharging techniques and methods such as constant voltage/resistance, constant current and constant power are addressed and analysed. The ultra- capacitor charging and discharging process is not a loss-free process. The charging/discharging losses equations are derived and discussed. Thermal models of the ultra-capacitor are also addressed. With the theoretical analysis, practical examples, and exercises presented, this chapter gives an overview of how an ultra-capacitor operates as energy storage device and what are the essential properties to be consider in design of a power conversion system. The chapter is concluded with an overview of state of the arte ultra- capacitor technologies as well as ultra-capacitor under short and long term development.

  • Power Conversion and Energy Storage Applications

    The fundamentals of power conversion, static power converters and power conversion applications are presented and discussed in this chapter. The need for integration of a short term energy storage device into a power conversion system is identified and selection of an appropriate energy storage device discussed. Ultra-capacitors and electrochemical batteries, as two major rivals are compared and the selection guide-line is given. Power conversion applications such as controlled electric drives, renewable sources (Wind, PV and Marine?>current?> generator), power generation and transmission devices (STATCOM), home appliances, mobile diesel electric gen-sets, UPS, earth moving machines and traction drives are applications that require integration of a short term energy storage into the system. These applications and the energy storage integration techniques are discussed intensively case by case. Benefits and advantages of having integrated energy storage are also discussed.

  • Energy Storage Technologies and Devices

    An energy storage device is a multi-physic device with ability to store energy in different forms. Energy in electrical systems, so-called?>electrical energy?>, can be stored directly or indirectly, depending on the means of the storage medium. Devices that store the electrical energy without conversion from electrical to another form of energy are called direct electrical energy storage devices. Two major energy storage devices are ultra-capacitor energy storage (UCES) and super-conducting magnetic energy storage (SMES). Devices that convert and store the electrical energy in another form of energy are called indirect electrical energy storage devices. Electro-mechanical storage devices are flywheels, compressed air energy storage (CAES) and hydro pumped energy storage (HPES). Electrochemical energy storage devices are electrochemical batteries and fuel cells. Above mentioned energy storage technologies and devices are briefly described in this chapter. Different fields of application are also discussed.

  • Interface DC-DC Converters

    In this chapter, interface dc-dc converters for ultra-capacitor energy storage applications are discussed. The background of dc-dc power conversion is given and different converter concepts and topologies are briefly compared. Topology selection process and guideline are given. The theoretical background of two- cell interleaved dc-dc converters is given. The operating principle is described in detail. The analysis is then extended to a general N-cell interleaved dc-dc interface converter. The converter's main parameters, such as the output current ripple and the dc bus current ripple, are analyzed and the solution is given as closed form equations. To give practical value to this chapter, the converter design procedure is discussed in great detail. The design and selection of passive components, such as the output filter inductor and coupling transformer (ICT), the dc bus capacitor and output filter capacitor, are described step by step. The selection process of power semiconductors is also addressed step by step. At the end of the chapter, thermal management of power converters is discussed in general. The origin of the conversion losses and the loss mechanisms in power semiconductors, transformers, inductors, and capacitors is fully addressed. With the theoretical analysis, practical examples, and exercises presented, this chapter gives a clear overview of how to select and design an interface dc-dc converter for ultra-capacitor energy storage applications.

  • Chapter 4 Asymmetrical Capacitors for Electric Propulsion

    Aviation propulsion development continues to rely upon fossil fuels for the vast majority of commercial and military applications. Until these fuels are depleted or abandoned, burning them will continue to jeopardize air quality and provoke increased regulation. With those challenges in mind, research and development of more efficient and electric propulsion systems will expand. Fuel-cell technology is but one example that addresses such emission and resource challenges, and others, including negligible acoustic emissions and the potential to leverage current infrastructure models. For now, these technologies are consigned to smaller aircraft applications, but are expected to mature toward use in larger aircraft. Additionally, measures such as electric/conventional hybrid configurations will ultimately increase efficiencies and knowledge of electric systems while minimizing industrial costs. Requirements for greater flight time, stealth characteristics, and thrust-to-power ratios adds urgency to the development of efficient propulsion methods for applications such as UAVs, which looks to technologies such as asymmetrical capacitors to enhance electric propulsion efficiency. This book will take the reader through various technologies that will enable a more- electric aircraft future, as well as design methods and certification requirements of more-electric engines.

  • High Temperature Performance of Polymer Film Capacitors

    The development of compact, thermally stable, high energy density, power conditioning capacitors has been identified to be one of the most difficult technological barriers in the design of high temperature electronic systems. High energy density capacitors are made of multiple, very thin layers of high dielectric constant insulating material. However, the polymer insulating films which are mechanically and electrically stable to the highest temperature, such as polyimide and teflon, also have the lowest dielectric constants and are the most difficult to make in very thin layers. This paper presents the collected results of research efforts to characterize and improve the high temperature performance of polymer capacitors. Temperature boundaries and the variation in dielectric properties with temperature and time are identified for a number of these films.

  • Electrical Characterization of Glass, Teflon, and Tantalum Capacitors at High Temperatures

    Dielectric materials and electrical components and devices employed in radiation fields and space environment are often exposed to elevated temperatures among other things. These systems must, therefore, withstand the high temperature exposure while still providing good electrical and other functional properties. In this work, experiments were carried out to evaluate glass, teflon, and tantalum capacitors for potential use in high temperature applications. The capacitors were characterized in terms of their capacitance and dielectric loss as a function of temperature up to 200 °C. At a given temperature, these properties were obtained in a frequency range of 50 Hz to 100 kHz. DC leakage current measurements were also performed in a temperature range from 20 to 200 °C. The results obtained are discussed and conclusions are made concerning the suitability of the capacitors investigated for high temperature applications.
