Zero-Voltage Switching Full-Bridge Converter With Reduced Filter Requirement and Wide ZVS Range for Variable Output Application

IEEE Transactions on Industrial Electronics, 2022
In this paper, a novel zero-voltage switching (ZVS) full-bridge converter is proposed to overcome the disadvantages of traditional phase-shifted full-bridge (PSFB) converter. In the proposed converter, a half-bridge (HB) converter with center-tap rectifier (CTR) is integrated into the traditional PSFB converter by sharing the lagging-leg switches and ...

A Zero Voltage Switching SVM (ZVS–SVM) Controlled Three-Phase Boost Rectifier

IEEE Transactions on Power Electronics, 2007
A zero voltage switching space vector modulation (ZVS-SVM) controlled three-phase boost rectifier is proposed. A branch composed of one active switch, one resonant inductor and one clamping capacitor is added to the six-switch boost rectifier. In addition, a ZVS-SVM for the rectifier is proposed. It can effectively suppress the reverse recovery process

A novel zero voltage switched (ZVS) buck converter using coupled inductor

Canadian Conference on Electrical and Computer Engineering 2001. Conference Proceedings (Cat. No.01TH8555), 2002
A novel zero-voltage switched (ZVS) buck converter using a coupled inductor is proposed in this paper. An additional winding is added on the same core of the output filter inductor for the purpose of commutation. The output inductor current is kept in continuous conduction mode (CCM) with small ripple.

A DC voltage notching scheme for zero voltage switching (ZVS) of PWM inverters

Proceedings of 1994 IEEE Industry Applications Society Annual Meeting, 2002
This paper presents a DC voltage notching scheme for zero voltage switching (ZVS) of PWM inverters. The proposed scheme permits programmed DC voltage notching, i.e. the DC voltage can be brought to zero on command to facilitate ZVS of the inverter switches.

A Zero-Voltage-Switching (ZVS) push-pull DC/DC converter for UPS

The Fifth International Conference on Power Electronics and Drive Systems, 2003. PEDS 2003., 2004
This paper presents a control scheme that is very suitable for the DC/DC converter in uninterruptible power supply (UPS) systems. Based on this control scheme, a ZVS push-pull converter is proposed. With heavy load, or during the latter stage of battery discharge with light load, the DC/DC converter will operate with duty cycle fixed to near 0.5, thus ...
