A Novel ZVS-PWM Single-Stage Single-Phase AC/DC/AC Converter with High Power Factor

Chien-Ming Wang;Juing-Huei Su;J.B. Lio;Chia-Hao Yang

2005 International Conference on Power Electronics and Drives Systems
Year: 2005 | Conference Paper |
This paper proposes novel zero-voltage-switching pulse-width modulation (ZVS-PWM) single-stage single-phase ac/dc/ac converter to give high power factor and low current distortion on the rectifier side and provide clean and stable ac voltage on the inverter side. In the proposed converter, besides operating at constant frequency, all semiconductor devices operate at soft-switching without addition...Show More

A Novel ZCS-PWM Flyback Converter With A Simple ZCS-PWM Auxiliary Circuit

Chien-Ming Wang;Juing-Huei Su;Chia-Hao Yang

2005 International Conference on Power Electronics and Drives Systems
Year: 2005 | Conference Paper |
Cited by: Papers (1)
This paper proposed a novel zero-current-switching pulsewidth-modulation (ZCS-PWM) flyback dc/dc converter using a simple ZCS-PWM auxiliary circuit. The main switch and auxiliary switch operate at zero-current-switching turn on and turn off, and the all passive semiconductor devices in the proposed converter operate at zero-voltage-switching (ZVS) turn on and turn off. Besides operating at constan...Show More

A novel single-stage ZVS-PWM buck-boost inverter

Chien-Ming Wang;Yen-Nien Wang;Chia-Hao Yang

30th Annual Conference of IEEE Industrial Electronics Society, 2004. IECON 2004
Year: 2004 | Conference Paper |
A novel single-stage zero-voltage-switching pulse-width-modulation (ZVS-PWM) buck-boost inverter is proposed in this paper. The output voltage of the proposed inverter can be larger or lower than the DC input voltage, depending on the instantaneous duty-cycle. This property is not found in the classical voltage source inverter, which produces an AC output instantaneous voltage always lower than th...Show More

30th Annual Conference of IEEE Industrial Electronics Society, 2004. IECON 2004
Year: 2004 | Conference Paper |
Cited by: Papers (6)
A novel zero-voltage-switching pulse-width-modulation (ZVS-PWM) full-bridge transformer-isolated step-up/down converter is proposed in this paper. The output voltage of the proposed converter can be larger or lower than the DC input voltage, depending on the instantaneous duty-cycle. This property is not found in the classical full-bridge transformer-isolated converter. Furthermore, in the propose...Show More

Improved ZCS-PWM commutation cell for IGBTs application

Chien-Ming Wang;Juing-Huei Su;Chia-Hao Yang

IEEE Transactions on Aerospace and Electronic Systems
Year: 2004 | Volume: 40, Issue: 3 | Journal Article |
Cited by: Papers (3)
An improved zero-current-switching pulsewidth-modulated (ZCS-PWM) commutation cell is presented, which is suitable for high-power applications using insulated gate bipolar transistors (IGBTs) as the power switches. It provides ZCS operation for active switches and zero-voltage-switching (ZVS) operation for passive switches. Besides operating at constant frequency and reducing commutation losses, t...Show More
