Power recycler for DC power supplies burn-in test: design and experimentation

Proceedings of Applied Power Electronics Conference. APEC '96, 1996

Conventionally, the burn-in test of DC power supplies uses resistors as load. Consequently, all the energy involved is lost by heating, provoking still an additional energy waste with the air conditioning system. The power recycler is a power converter that replaces the resistors load banks in the burn-in test of DC power supplies with the advantage that most of the ...

  • Voltage enhancement of dc power supplies of superconducting coils of LHD

    The Large Helical Device (LHD) is a helical-type fusion plasma experimental device using six superconducting coils to form a magnetic field. The fundamental operation of the LHD is performed under a dc magnetic field, and a power system which was suitable for steady state excitation was designed and constructed. With the progress in the fusion plasma research, dynamic experiments such as sweep of magnetic axis are planned, and require dynamic control of magnetic field. For this purpose, the output voltage of the original power supplies were not enough and the voltage enhancement of the dc power supplies were necessary. Therefore, the output voltages of power supplies were enhanced using additional pulse power supplies and the control system was modified for the pulse operation.

The FIT exploits the power summing amplifier feature of op-amps embedded in the feedback control loop of dc-dc regulators, thus realizing a dynamic source and a dynamic load to observe the transient and AC response of another power supply connected to its input or output by means of an oscilloscope. Examples of line transient and load transient tests and PSRR measurements are presented in the paper, realized with the Texas Instruments PMLK Series BUCK and LDO boards, allowing an easy implementation of dynamic testing of power supplies based on the FIT concept.

    This paper discusses a cost-effective technique for dynamic testing of DC-DC power supplies, based on the injection of a signal into the feedback loop of a DC-DC regulator, which makes it operating as a dynamic source or a dynamic load. The theoretical background and the practical implementation of the technique are investigated. Guidelines are provided to determine the static set-up and the bandwidth of DC-DC regulators operating in dynamic source and dynamic load modes. Examples of experimental line and load transient tests of switching and linear DC-DC power supplies are realized by means of the Texas Instruments PMLK Series BUCK, BOOST and LDO boards.

  • Power recycler for DC power supplies burn-in test: design and experimentation

    Conventionally, the burn-in test of DC power supplies uses resistors as load. Consequently, all the energy involved is lost by heating, provoking still an additional energy waste with the air conditioning system. The power recycler is a power converter that replaces the resistors load banks in the burn-in test of DC power supplies with the advantage that most of the energy is sent back to the utility grid with low THD and quasi-unitary power factor. The economical benefits due to energy savings are evident and contribute in reducing the final cost of the equipment. Besides, the power recycler is totally agreeable to the world concern about ecology and energy conservation. This paper analyses the proposed solutions in recent literature and presents a new architecture for the implementation of a power recycler for DC power supplies burn-in tests. The proposed circuit is regulated by conventional integrated circuits: PWM and power factor controllers. Circuit operation, design characteristics, simulation and experimental results of a 2 kW prototype are provided in the paper.

  • Feedback injection-based technique for dynamic load/line tests of DC power supplies part II: Applications

    This paper discusses examples of application of the Dynamic Line/Load (DLL) emulation technique based on the injection of an external signal into the feedback loop of a dc-dc regulator, introduced and discussed in the companion paper Part I. Load transient and line transient tests on linear regulators have been realized by means of the Texas Instruments PMLK-LDO board, which allows an easy implementation of the DLL emulation technique and simplifies the dynamic testing of power supplies. The PMLK-LDO board used for the tests is based on the Texas Instruments TPS7A4901 and TPS7A8300 linear regulators.

  • Peak-current-mode based single-wire current-share multimodule paralleling DC power supplies

    In this brief, a peak-current-mode control based on the closed-form loop compensator design is proposed to integrate with a current-sharing circuit to automatically and smoothly adjust the trim signal in conventional dc/dc power supplies. As a result, for single-wire autonomous current sharing of paralleled dc power supplies, not only the minor alarm of the current limit can be avoided, but also the imbalance in current distribution during the transient state can be reduced. To demonstrate the effectiveness of the proposed method, an example of three 150-W parallel modules is considered. Experimental results are also presented to illustrate the proposed method.

  • The analysis of the occurrence of high in-rush currents in DC power supplies

    This paper uses detailed simulation models to investigate inrush current characteristics of typical dc power supplies, following various supply system voltage disturbances. Current methods of inrush current protection are investigated, and it is shown that careful consideration must be given to fuse selection in order to providing protect the dc power supply and avoid erroneous tripping. The paper also proposes a simplified equivalent model, based on an uncontrolled rectifier, for the accurate prediction of inrush currents considered dc power supply configurations.

  • Capacitor voltage controls of novel five-level inverter having only double DC power supplies

    The five-level PWM inverter has many advantages such as ability to operate the AC motors or the power compensator with very large capacity in nearly sinusoidal current waveforms. For these reasons, these applications have just begun to study. However, this circuit must provide four DC power supplies for supplying the active power. In this paper, we propose a novel double power supply method, in which both power supplies are inter-connected by DC capacitors. The voltages of the inter-connected DC capacitor are controlled by a novel third order harmonic injection method, where the phase of modified third order harmonic signal having positive or negative polarity is controlled individually
