Abstract

The advantage of three-level converter is that the voltage stress is only the half of input voltage. A DC-DC converter based on improved three-level topology combining soft-switching ZVZC PWM controlling is proposed in this paper. And the converter structure and working principle is analyzed. Through computer simulation the performance is evaluated and experimental results indicate that the proposed technique is correct and effective. The converter is very suitable for the situation of high power quality waveforms, low EMI and high voltage capability.
