“…Equation (24) shows that the polarity of iM will influence the extra added current i add . The expression of i M in (25) indicates that the polarity of iM is related to load currents, modulation voltages and different PWM methods. To analyze the impact of different operation conditions on the ZVS condition, the following assumption of three-phase modulation voltages and ac side currents in three-phase three-wire systems are made: sin sin sin 2 3 , sin 2 3 sin 2 3 sin 2 3 ma m z a m mb m z b m mc m…”

“…The energy stored in the resonant inductor can be accurately controlled to meet the ZVS conditions under different load situations. In recent years, ZVS-SPWM has been proposed for single-phase inverters and threephase inverter/rectifier with either 3-wire or 4-wires [24][25][26]. Meanwhile, the circuit operation principle and ZVS conditions are separately discussed in 3-wire and 4-wire systems according to SPWM and SVM schemes.…”

A general PWM method for soft-switching threephase power converters-Edge Aligned PWM (EA-PWM) is proposed. It aligns all the high loss commutation instants of the converter bridges in a switching cycle at the same instant so that all the switches of the three-phase converter can realize zerovoltage-switching (ZVS) with the help of the resonant auxiliary circuit which operates once each switching cycle. EA-PWM scheme for ZVS active-clamping three-phase converter is introduced. ZVS condition and voltage stress of the converters is derived. EA-PWM can adapt to various modulation methods such as SPWM, Harmonic Injected SPWM, Continuous Pulse Width Modulation (CPWM), Discontinuous Pulse Width Modulation (DPWM), etc. The ZVS condition of three-phase Compound Active Clamping (CAC) converter are discussed. Finally, EA-PWM scheme is verified in Back-to-Back (BTB) converter prototype.

“…To overcome the drawbacks of the DC resonate link inverter, a novel fixed-switching-frequency zero-voltageswitching pulse width modulation (ZVS-PWM) technique for the DC-side resonation method has been investigated in [12][13][14][15]. In the proposed zero-voltage-switching (ZVS) technique, only one simple auxiliary circuit is employed to realize the ZVS operation for all power switching devices.…”

Power electronic conversion plays an important role in flexible AC or DC transmission and distribution systems, integration of renewable energy resources, and energy storage systems to enhance efficiency, controllability, stability, and reliability of the grid. The efficiency and reliability of power electronic conversion are critical to power system applications. One way to enhance the efficiency and reliability of power electronic conversion is soft-switching technology. This paper introduces a generic zero-voltage-switching (ZVS) technique based on silicon carbide (SiC) power device. Using the proposed ZVS technique, all semiconductor switching devices in a power converter can realize ZVS operations. Next, the applications of the ZVS technique in different power electronic conversion systems such as photovoltaic inverters, wind power systems, energy storage systems and flexible AC transmission system devices are discussed. Finally, as an example, the operation performance and efficiency improvement of a SiC metal-oxide-semiconductor field-effect transistor (MOSFET) ZVS back-to-back converter are discussed.
