A ZVS and ZCS DC-DC converter based on weinberg topology for high voltage applications

This paper proposed a zero voltage and zero current switching (ZVS, ZCS) dc-dc converter based on Weinberg topology. The voltage spike at turn off instant is suppressed by active clamp snubber (ACS), and this circuit is also take part in soft switch operation. With the simple active clamp circuit, high efficiency and power density could be achieved under 800V output voltage. And the conclusion is combined with experimental results for analysis.
