| 摘 要： | 提出一种移相控制有源箝位全桥Boost倍压变换器(Phase-ShiftActive-clampFull-bridgeDouble-VoltageConverter,PSAFBDVC)。有源箝位网络抑制了桥臂间的电压过冲,移相控制实现了开关管的零电压/零电流开关。该电路电压增益高,适用于高压输出的场合。文中对PSAFBDC的工作状态、工作时序进行了详细分析,并给出了电路实验波形。实验结果证明了PSAFBDVC实现高压电源可行性。

| Abstract: | A novel power converter,Phase-Shift Active clamp Full-bridge Double-voltage Converter(PS AFBDC) is proposed.The Active clamp network restrains the voltage overshoot,and phase-shift control realizes zero-voltage and zero-current switch.It has the characteristic of high voltage gains and suits to high-output-voltage power supply.In the paper,the operating principle,operating modes and direct current modes are described in details.The practical design waveform of the circuit is given.The experimental results show that the proposed converter is practical. |
