Input-series-output-parallel (ISOP) inverter system is very suitable for high input voltage and high output current power conversion applications. The control objective of the system is to achieve input voltage sharing (IVS) and output current sharing (OCS) among the constituent modules. Aiming at the target, this paper presents a novel compound control strategy, i.e., the method entitled input voltage sharing combined with the same inductor current amplitude. In the proposed scheme, the phase of inductor current and accordingly the active power of each module are regulated by IVS loop based on the deviation between input voltage of respective module and average input voltage. And meanwhile, the amplitude of each inductor current is kept the same and so the OCS is realized. Furthermore, a new solution dedicated to distributed configuration is put forward, and the communications among the modules are realized through three buses. The experimental results validate the effectiveness of the control strategy and the distributed configuration.

An advanced LLC series resonant converter (SRC) with resonant switched-capacitor technique is proposed in this paper to satisfy the high voltage and high step-down requirements. The series structure in the high-voltage side, together with a switched capacitor and its resonant inductor, effectively reduces the voltage stress on the high-side switches to half of the input voltage, which enhances the capability of handling high voltage. Furthermore, high DC voltage step-down conversion is achieved through the combination of the resonant switched capacitor technique and the LLC resonant technique. All the main switches in the proposed converter can achieve zero voltage switch (ZVS) turn-on performance and all the rectifier diodes can achieve zero current switch (ZCS) turn-off performance from no load to full load with wide-input-voltage range. Besides, the conduction loss of the power switches is reduced by half, which can further improve the efficiency of the converter. Finally, a 500V~640V-input 48V-output 900W prototype is designed and built to verify the effectiveness of the proposed converter. The results have proved that the proposed converter is an excellent solution for high efficiency, high power density, high voltage and high step-down conversion.

A large capacity PCS (Power Conditioning System) applied to PMSG (permanent magnet synchronous generator) of wind turbine has been developed and the operation characteristics of the PCS were tested with the same conditions in actual field operation. The low voltage ride through capability that required in each country grid code was evaluated by a digital simulation and a simulator test with a scale-down model of PCS installing actual control card, a motor generator set and grid simulator. It was confirmed that the PCS continuously operate without disconnection during the low voltage condition simulated by the grid simulator. Then the LVRT capability for actual 2MW-PCS is also evaluated with the digital simulation.

Based on the stability analysis methodology for cascade converters, the photovoltaic (PV) interface stability of current-fed (CF) maximum power point tracking (MPPT) converter adding input capacitor is studied, and the interface voltage control loop design guideline is given in this paper. The interface stability criterion of cascade system composed of PV cells and the MPPT converter is deduced at first, and then the output impedance of photovoltaic cells and the closed-loop input impedance of the Boost converter adding input capacitor are analyzed. According to the stability criterion proposed here, the stability conditions together with the design guidelines-the controller parameter of the CF MPPT converter adding input capacitor should be design under the minimum interface voltage to ensure the converter maintain the PV interface stability in the entire input voltage range-for the MPPT converter are derived. The validity of the theoretical analysis has been verified by the experiments on a 150W prototype.

A multi-input DC/DC converter based on coupled inductor is proposed in this paper. An interleaved bidirectional buck-boost converter and a full bridge converter are integrated together to derive a combined three-port DC/DC converter. The power density is improved and the circuit structure is simplified because the power devices are completely shared in the primary side and the two filter inductors in the bi-directional buck-boost converters and the isolated transformer in the full-bridge topology are integrated and replaced by the coupled inductors. Furthermore, the pulse width modulation (PWM) plus phase-shift (PPS) control strategy is introduced to achieve the decoupled voltage regulation within a certain operating range. The duty cycle of the bi-directional buck-boost converters is adopted to balance the voltage between the two primary input terminals, while their phase angle is applied to regulate the accurate secondary voltage. Finally, a 1 kW prototype is built to verify all theoretical considerations and it is shown that the proposed topology is particularly advantageous in the distributed power generation system with multiple energy sources.

The three-phase dual-active bridge (DAB3) is a dc-dc converter, which is most suitable for high-power applications, as it features inherent soft switching and bidirectional power flow. The medium-frequency three-phase transformer in the ac link of the converter allows galvanic isolation and an arbitrary voltage conversion ratio. This work discusses asymmetric impedances in high-power medium-voltage transformers and their influence on the DAB3. Especially in high-power applications, asymmetries in the impedance occur, due to bigger dimensions of the transformer and holding on to conventional transformer designs. Considering the DAB3, due to unequal stray inductances in the transformer, a second harmonic component can be observed on the dc currents. Thereby, the ripples on the dc voltages and losses in the dc link capacitors are increased unnecessarily. This effect is demonstrated in this work using a laboratory prototype. A new approach is presented, which allows compensation of these effects and optimizes the performance of the DAB3 for asymmetric transformers. The concept of this balancing method is to control each of the interacting phases. The control includes solving an optimization problem, which is too complex to be calculated in real time on a digital signal processor (DSP). To ensure realizability on a DSP, a simplified approximation of this approach is presented as well. Finally, the added value of the proposed balancing control and the comparison with the simplified control are quantified through simulation and measurement.

Bi-directional inductive power transfer (BDIPT) technique is attractive for applications, such as electric vehicles (EVs), for the realization of vehicle-to-grid (V2G) systems. This paper presents a circuit topology to individually control magnitude and direction of power flow from grid to multiple EVs. The proposed system employs two inductor-capacitor-inductor (LCL) parallel resonant circuits together with a segmented switching converter and two pick-ups, to facilitate individual control of power flow. A mathematical model is presented, showing the individual controllability of bi-directional power flow between the tracks and the pick-ups. Validity of the proposed concept is demonstrated through simulation results of a 1.5 kW IPT system. Results indicate that the proposed topology is feasible, and ideal for applications where bi-directional power flow needs to be controlled individually within `N' numbers of tracks and pick-ups.

A novel control scheme using space vector modulation for a multilevel modular matrix converter is proposed. According to this control scheme, the increase in amount of calculation as the number of cells increases can be moderately suppressed. Moreover, a capacitor voltage balancing control is also employed, which ensures the operation even under the condition input and output frequencies are almost the same. To verify the proposed control scheme, numerical simulation is carried out. In addition, experimental results of 60/50 Hz and 60/60 Hz conversions using a 1 kW modular matrix converter which consists of 9 H-bridge cells are presented.

Recently, many energy-saving household appliances such as air conditioners, refrigerators, and LED bulbs are being used in residences. Most household appliances use diode rectifiers equipped with smoothing dc capacitors, which cause the passage of a large harmonic current through utility lines. This harmonic current may cause electrical equipment to malfunction or fail. Because the household appliances are connected to the single-phase utility grid, the third-harmonic component is dominant among the harmonic current generated by the appliances. However, the fifth-harmonic component generally is dominant in distortion contained by the utility voltage of power distribution lines. This paper discusses the flow of the third-harmonic current in three-phase three-wire system. As a result, if only the one conventional single-phase active filter is connected to the distribution system, the third-harmonic current may increase in the system. To solve this issue, the authors propose a control strategy of single-phase active filters. Furthermore, the validity of the proposed control strategy is shown by the experiment and simulation results.
