摘要：

A high-voltage dc-dc converter with low voltage stress on the power switches and high output current capacity is presented. This converter exhibits three distinct features. First, the voltage stress on the primary switches is only one-third of the input voltage, so that switches of low voltage rating and thus of low on-resistance can be used. This leads to reduced conduction loss. Second, all the switches are soft-switched, so that the switching loss can be reduced. Third, the rectifier is a current tripler, so that the output current capacity, and thus the power handling capacity of the converter are increased. A 5.1-kW, 1000-V/48-V dc-dc converter prototype has been built and tested. Experimental results are favorably compared with theoretical predictions.
