Voltage Switching

In this research, a high-voltage direct current zero voltage switching (ZVS) PWM half-bridge converter is proposed. The parameters of the converter as follows: the input voltage is up to 4000V;the output voltage is 600V.The new ZVS PWM TL converter has neutral point clamping diodes and flying capacitor. This research is going to analyze the working principle of circuit witch thus realizing the zero voltage switching and the circuit parameters selection. Moreover, circuits simulation is carried out by MATLAB to verify the reliability and feasibility of this DC/DC converter topology.
