摘　　要：文章对一种升压变换器拓扑——全桥并联谐振倍压变换器进行了分析。该变换器通过电路谐振实现了开关管的零压开通,提高了变换器的效率。通过对该变换器的稳态工作过程分析及理论推导,得出了该变换器的零电压条件与电压增益曲线,并通过PSPICE仿真,验证了结论的正确性。The Full-bridge Parallel resonant Dual-voltage Converter, a high-voltage converter topology is presented. The converter realizes Zero-Voltage-Switching by resonant of the circuit which increases the efficiency of converter. The steady-state of the circuit is analyzed and deduced, the ZVS- condition of the converter and voltage-gain curve are given. Also a PSPICE simulation is carried out, and then the results are validated.
