摘　　要：提出了一种新型具有四种模式的交流-交流变换器,该变换器在新模式输出波形上降低了谐波,提高了输出电压的质量,减小了电压的纹波,同时增加了新的工作模式。在新的工作模式下,该变换器具有原变换器只用两个开关管高频切换、减少了电能损失等优点,适用于特殊的场合。介绍了该变换器的工作原理和控制方式,对新模式的电感电容进行了推导,并在MATLAB/Simulink中仿真验证了其正确性。This paper proposes a new type of AC-AC converter with four modes which reduces harmonics in the output waveform of the new mode,improves the quality of the output voltage,reduces the damage of voltage ripple to electrical appliances,and adds a new operating mode.Under the new operating mode,this converter inherits other advantages of the original converter,such as only using two switching tubes for high-frequency switching and reducing power loss.The working principle and control method of the converter are outlined in this paper,the inductance and capacitance of the new mode are derived,and the correctness is verified through simulation in MATLAB/Simulink.
