摘　　要：提出了一种新颖的适用于航空变频电源(360～800 Hz)的AC/AC变换器。它由双升压式整流器和双降压式逆变器直接连接构成,继承了无桥臂直通隐患、无体二极管反向恢复的优点,同时具有可靠性高和效率高的优点。简要介绍了该变换器的工作原理和控制方法;推导了前后级电感的设计公式;仿真和实验验证了理论分析的正确性。A novel dual Boost/dual Buck AC/AC converter which is very suitable for the variable frequency AC source of airplane（360～800 Hz） is proposed.It is constructed by directly connection of a dual Boost rectifier and a dual Buck inverter which inherit the merits of high reliability and efficiency of them for no hidden danger of shoot-through and no freewheeling current flows through the body diodes of power switches.The operational principle and control method are briefly introduced, and then the method of designing inductors is deduced.Simulation and experiments verify the validity of the theoretical analysis.
