摘　　要：介绍了一种零电压零电流开关(ZVZCS)全桥DC/DCPWM变换器。通过设计宽幅压直流变换器电路,验证了全桥PWMZVZCS变换电路在调整幅压、减小占空比丢失及消除电路环流等方面无可替代的优越性。A ZeroVoltage ZeroCurrentSwitching(ZVZCS) fullbridge pulse width modulation converter is discussed.The design of an wide range direct current converter proved that the ZVZCS fullbridge converter is indubitable superior in the adjusting the voltage amplitude,reducing the lossofduty cycle and eliminating the circumfluence of the circuit.

关 键 词：变换器 脉宽调制 占空比
