  • Power Management In Solar PV Fed Microgrid System With Battery Support

    Installation of renewable resources at single phase residential premises calls on for the need of power management and coordination control of operating system. System is divided components which includes, solar PV maximum power point tracking (MPPT) via boost converter, bi-directional DC-DC converter for battery charging applications, and bidirectional AC-DC converter for feeding AC loads, etc.,. This paper, elaborates the solar PV alongside with battery power management scenario so as to form a sophisticated residential consumer system capable of operating in both grid forming (or, islanded) and feeding (or, grid connected) modes. System is tested via PSCAD based simulation platform, for operation in varying operating modes such that the power could be fed from DC to AC microgrid and vice-versa. DC-AC converter operating in closed loop sine pulse width modulation (SPWM) scheme, is used to control AC side voltage while operating in islanded mode. It works in rectification mode during grid connected mode. In day time, system is in islanded mode where excess / deficit power is exchanged with energy storage unit (ESU). In evening or night time, it operates in grid connected mode so as to charge the ESU.

  • Derivation of a global model of a two-stage photovoltaic microinverter using sliding-mode control

    This paper develops a global model of a two-stage grid-connected microinverter which uses sliding-mode control laws in both stages. In the study, it is considered that the microinverter is fed by a current source representing the photovoltaic module with a capacitor connected in parallel. The model of the DC-DC stage is obtained from the linearization of the ideal sliding dynamics of the converter considering that it is controlled through the input current. The DC-AC stage tied to the grid is considered as the load of the DC-DC stage. This representation allows including the voltage regulation loop used to stabilize the DC-link voltage through the value of the output current. The model is used to evaluate the local stability of the DC-link of the microinverter which represents the power balance of the system. The results are validated by means of simulations and experimental results.

  • A High Efficiency Quasi-Single-Stage Unified Power Quality Conditioner Integrating Distributed Generation

    A novel quasi-single-stage unified power quality conditioner integrating distributed generation (UPQC-DG) is proposed in this paper. With the help of quasi-single-stage architecture, the low-voltage distributed generation, e.g., PV modules or energy storages, can directly supply active power to the ac grid or ac load within single power conversion stage. Therefore, in comparison with traditional two-stage UPQC-DG, the power conversion stages are reduced and the overall conversion efficiency is enhanced. A modified SVPWM strategy aiming at realizing most active power transferred within single power conversion stage is discussed. Besides, the power flow through the quasi-single-stage UPQC-DG is analyzed in detail to understand the system operation and design the power converters properly. Experimental results with a 3kVA prototype are provided to verify the feasibility and effectiveness of the presented quasi-single- stage UPQC-DG.

  • A high-voltage DC-DC converter with low-voltage stress and output current tripler

    A high-voltage dc-dc converter with low voltage stress on the switches and output current tripler is presented in this paper. This converter exhibits three distinct features. First, the voltage stress on the switches is only one-third of the input voltage, so that switches of low voltage rating and thus of low on-resistance can be used. This can reduce the conduction loss. Second, all switches are soft-switched, so that the switching loss can be reduced. Third, the output circuit is a current tripler, so that the output current capacity and thus the power handling capacity of the converter are increased. A 4.8kW, 1000V/48V dc-dc converter prototype has been built and tested. Experimental results are favorably compared with theoretical predictions.

  • High Gain, High Frequency Link DC-AC Converter with Hybrid SPWM Scheme

    A high gain, single-stage DC-AC converter with high frequency AC link is proposed in this paper. The single-stage DC-AC converter has the advantage of high efficiency, less component count and high power density. The proposed converter consists of a high frequency switching buck-boost bridge followed by a low frequency switching cycloconverter. A hybrid sinusoidal PWM switching scheme is used for the buck-boost bridge to control the output and to mitigate the DC-current in the transformer primary winding. In the proposed converter, soft transition is achieved in all the devices. The steady-state voltage gain achieved is twice that of the conventional H-bridge phase-shift converter. The input current is continuous in the proposed converter which reduces the DC bus capacitor requirement for solar PV fed applications. The steady-state analysis with the modes of operation of the proposed converter are presented. A 2 kVA proposed converter feeding the R and RL load is designed and implemented in the simulations and the analytical model is verified. The comparison studies of the proposed converter with the topologies in literature are presented.

  • Single stage DC-AC boost converter

    This paper presents a new DC-AC converter which not only acts as inverter but also boosts the output voltage with respect to input. This topology is cost- effective due to reduced switch number and it is suitable for compact design. Switching strategy in this topology is similar to conventional inverter and in each half cycle, boost operation is done by one of the two boost converter. Variable duty cycle is applied for generating sinusoidal output voltage. Theoretical analysis and operation principle are presented together with simulated results to validate the proposed concepts.

  • Advanced PWM Switching Technique for Accurate Unity Power Factor of Bidirectional Three-Phase Grid-Tied DC-AC Converters

    Matrix-based high-frequency linked (MBHFL) bidirectional dc-ac converters are getting much interest in grid-tied applications due to their high efficiency and the compacted footprint. This paper proposes a new PWM switching technique of the MBHFL dc-ac converters based on phase shift angle considering compensation of the LC filter current at the grid side in order to realize accurate unity power factor and to reduce the total harmonic distortion (THD) of the grid current waveform. The proposed technique estimates the phase shift angle error between the grid voltage and current waveforms due to the capacitor injected current that reduces the power factor at the grid side. It considers two operational modes based on the patterns of three-phase grid voltage and current waveforms. Therefore, it provides the matrix converter switches with different duties according to the pattern of the detected grid voltage and the reference grid current to compensate the phase shift angle error. Also, grid LC filter design and the system controllable limit of the matrix converter output voltage are presented. In addition, the PWM switching technique of the H-bridge circuit is modified to realize safe operation of the converter during step changes at the grid voltage. The effectiveness of the proposed PWM switching technique and its related mathematical model have been investigated experimentally using laboratory prototype based 200V, 2kW.

  • Five-level T-type NPC PFC rectifier based on multistate switching cell

    This paper presents a proof of concept of a new converter cell named T-type multistate switching cell (TT-MSSC). The proposed cell was derived from the three-phase current fed DC-DC Push-Pull converter with NPC output rectifier and can provide both AC-DC and DC-AC conversions for single-phase, three-phase or multi-phase configurations. Based on the proposed cell, a single-phase unidirectional converter is proposed which provides the following features: power factor correction, current sharing through devices, symmetrical voltage division across semiconductors, inductor current ripple with twice switching frequency, and five level voltage formation between ground point and common point of the autotransformer. To verify the operation principle, a prototype with the input voltage Vi = 220 V (rms), output voltage Vo = 800 V, and output power Po = 1 kW was implemented and tested in laboratory.
