Zero-voltage-switching single-Phase Inverter with active power decoupling
2018 IEEE Applied Power Electronics Conference and Exposition (APEC), 2018Co-Authors: Yenan ChenAbstract:Active Power Decoupling (APD) is used for single-Phase Inverter to cope with the double-line frequency power pulsation in the Inverter DC side. In this paper, zero-voltage switching (ZVS) for the single-Phase Inverter with APD is introduced. A ZVS SPWM scheme for single-Phase Inverter with APD is proposed. The operation of the ZVS single-Phase Inverter with APD is analyzed and ZVS conditions are derived. Finally, a 500kHz 1.5kW prototype is built to verify the theoretical analysis.

Pulse-width modulation scheme for a ZVS single-Phase Inverter in rectifier operation
2018 IEEE Applied Power Electronics Conference and Exposition (APEC), 2018Co-Authors: Yenan ChenAbstract:This paper proposes a new pulse-width modulation scheme for a Zero-Voltage-Switching (ZVS) single-Phase Inverter to operate in rectifier mode. The ZVS single-Phase Inverter and its ZVS-SPWM modulation scheme is reviewed. The commutation in rectifier mode is analyzed to design the proper modulation scheme. ZVS turn-on of switching devices is achieved as well as the reverse recovery of body-diode is relieved with the new modulation in rectifier mode. The principle of ZVS rectifier operation is explained in detail and verified on a 100kHz ZVS single-Phase Inverter prototype. The modulation scheme of rectifier operation makes the ZVS single-Phase Inverter suitable for bidirectional power conversion applications such as energy storage system and vehicle-to-grid (V2G) chargers.

A ZVS-PWM Single-Phase Inverter Using a Simple ZVS-PWM Commutation Cell
IEEE Transactions on Industrial Electronics, 2008Co-Authors: Chien-ming Wang, Maoh-chin Jiang, Yan-chun LinAbstract:A new zero-voltage-switching (ZVS) pulsewidth-modulated (PWM) single-Phase Inverter using a simple ZVS-PWM commutation cell is presented in this paper. Except for the auxiliary switches, all switching devices in the ZVS-PWM single-Phase Inverter operate at ZVS turn on and turn off. The auxiliary switches operate at zero-current-switching turned-on and turned-off. Besides operating at constant frequency, the proposed Inverter has no overvoltage across the switches on the main switch compared to the hard switching Inverter counterpart. Auxiliary components rated at very small current are used. The principle of operation, theoretical analysis, and experimental results of the new ZVS-PWM single-Phase Inverter, rated 1 kW and operated at 40 kHz, are provided in this paper to verify the performance.

Analysis and design of a soft-switching single-Phase Inverter and three-Phase modular connection for Inverters
2009 International Conference on Power Electronics and Drive Systems (PEDS), 2009Co-Authors: Maoh-chin Jiang, Chien-ming Wang, Shyh-shing Perng, Yung-chun Hung, Ming-lang SyuAbstract:This paper presents a zero-voltage-switching (ZVS) pulse-width-modulated (PWM) single-Phase Inverter and the establishment of a V-connected three-Phase Inverter using two such single-Phase modules. All main switches in the ZVS-PWM Inverter operate at ZVS turn-on. The auxiliary switches operate at zero-current-switching (ZCS) turn-off. Since commutations of the main power devices occur with low losses, higher efficiency is achieved. Moreover, two single-Phase ZVS-PWM Inverter modules are then connected to form a V-connected soft-switching three-Phase Inverter. Some experimental results are presented for verification.

Influence of DC Link Capacitance on Power Efficiency of Single-Phase Inverter
2018 IEEE Energy Conversion Congress and Exposition (ECCE), 2018Co-Authors: Yi Liu, Huai Wang, Meng Huang, Xiaoming Zha, Yushuang LiuAbstract:The capacitor sizing for the capacitive DC link of a single-Phase Inverter is usually based on a pre-determined voltage ripple limitation, ripple current capability, and/or energy storage requirement. Nevertheless, it is lack of justifications of the pre-determined criteria. This paper aims to investigate the dependency between the DC-link capacitance and the converter-level efficiency of a single-Phase Inverter. The major sources of the converter power loss, i.e., IGBTs, capacitors, and inductors, are quantitatively modeled considering the varying DC-link voltage. It provides an additional dimension to optimize the capacitor selection for capacitive DC links. The theoretical analyses are verified by both simulations and experiments.
