Zeta Converter with Resistor-current-diode Snubber and H-type Snubber to Reduce Switching and Reverse-recovery Losses

Cheng-Tao Tsai and Ji-Xin Chen

(Received June 27, 2020; Accepted January 6, 2021)

Keywords: resistor-capacitor-diode (RCD), zero-voltage transition (ZVT)

In this paper, a zeta converter with a resistor-capacitor-diode (RCD) snubber and an H-type snubber to reduce switching and reverse-recovery losses is proposed. The proposed converter has the following advantages: 1) By incorporating an RCD snubber, the power switch can achieve a zero-voltage transition (ZVT) to reduce the switching losses of the power switch. 2) By incorporating an H-type snubber, the reverse-recovery losses of the power diode can be reduced. Therefore, the overall efficiency of the proposed converter is increased significantly. Finally, a prototype zeta converter with an RCD and an H-type snubber to reduce the switching losses of the power switch and the reverse-recovery losses of the power diode is built. Experimental results verify that the proposed zeta converter is relatively suitable for the requirements of a low or medium power.
