“…This restriction limits the references for modulation in operating the power converters at the same frequency. Voltage doubling and semiconductor stress are not issues in the B4 converter, unlike in the nine-switch H6 converter, because of the favorable maximum modulation ratio of unity [215]. (4) Reduced switch count (four-switch) topologies face more limitations in their switching states than conventional six-switch converters.…”

Abstract:This study summarizes an analytical review on the comparison of three-phase static compensator (STATCOM) and active power filter (APF) inverter topologies and their control schemes using industrial standards and advanced high-power configurations. Transformerless and reduced switch count topologies are the leading technologies in power electronics that aim to reduce system cost and offer the additional benefits of small volumetric size, lightweight and compact structure, and high reliability. A detailed comparison of the topologies, control strategies and implementation structures of grid-connected high-power converters is presented. However, reducing the number of power semiconductor devices, sensors, and control circuits requires complex control strategies. This study focuses on different topological devices, namely, passive filters, shunt and hybrid filters, and STATCOMs, which are typically used for power quality improvement. Additionally, appropriate control schemes, such as sinusoidal pulse width modulation (SPWM) and space vector PWM techniques, are selected. According to recent developments in shunt APF/STATCOM inverters, simulation and experimental results prove the effectiveness of APF/STATCOM systems for harmonic mitigation based on the defined limit in IEEE-519.

“…In [24], the loss distribution of various components was investigated in detail, and both the power switching devices and the passive components were studied. In [25,26], the switch and diode loss are studied and compared in detail for several converter topologies, and the specific loss distribution of the corresponding topology is also given. In [27], the losses of diodes with various materials is compared, and the loss distribution based on the corresponding topology is also given.…”

“…For power converters, especially for the high frequency applications, the loss analysis is crucial due to its guiding significance for the efficiency estimation and magnetic design [24][25][26][27][28][29][30]. Therefore, an increasing number of scholars have focused their attention on the loss analysis for various converters.…”

Based on the loss distribution and efficiency analysis, a comparative study between a series resonant three-port bidirectional DC-DC converter (SR-TBC) and a multi-resonant three-port bi-directional DC-DC converter (MR-TBC) is reported here. By using the Fourier equivalent analysis method in hand, the resonant current, switching current expressions, zero voltage soft switching (ZVS) conditions of MR-TBC and SR-TBC are deduced. Besides, in consideration of efficiency and soft switching aspects, the loss models of main power components and resonant elements are integrated and optimized for both topologies. Their loss distributions are established, and the different effects derived from the adoption of SiC MOSFET and Si MOSFET on the converter efficiency are discussed. Finally, to verify the theoretical analyses, comparative experiments under diverse load states are conducted based on the prototypes of the MR-TBC and SR-TBC. The obtained results demonstrate that the MR-TBC successfully broadens the ZVS range and thus achieves higher efficiency along the entire load range.

“…Some papers have proposed topologies of converters with reduced number of switches to supply single-phase loads [ [15], [16], two-phase loads [17] and three-phase loads [18]- [20]. The high number of power switches increases the converter complexity, costs and reduces the reliability.…”
