As the Three-level ZVS-PWM DC-DC converter operates likewise full-bridge ZVS-PWM DC-DC converter nod the blocking voltage of each switching device is a half of the DC-Iink voltage, it is suitable foc the high input voltage applications. However, it has some problems as follows, The blocking voltage of each devices is unbalanced and it causes the power losses of the inner switching devices to be increased. Also, It has narrow load range so that the switching losses nod the efficiency are reduced as it goes to the light load. This paper presents a novel Three-Ievel ZVS-PWM DC-DC converter, which can reduce the overvoltage of the outer switches, eliminate the unbalance of the voltage sharing between the switches at turn-off doe to the stray inductances, and operate from no load to full load. The characteristics nod the performances of the proposed Three-level ZVS-PWM DC-DC converter are verified by simulation and experimental results.
