从十九世纪末到二十世纪中叶，直流电到交流电的转换是用旋转变换器或电动发电机组（M-G机组）来完成的。在二十世纪早期，真空管和充气管开始在逆变电路中用作开关。最广泛使用的管子是闸流管。机电逆变器的起源解释了逆变器一词的来源。早期的交直流变换器采用感应式或同步式交流电动机直接连接到交流发电机上
From the late nineteenth century through the middle of the twentieth century, DC-to-AC power conversion was accomplished using rotary converters or motor-generator sets (M-G sets). In the early twentieth century, vacuum tubes and gas filled tubes began to be used as switches in inverter circuits. The most widely used type of tube was the thyratron. The origins of electromechanical inverters explain the source of the term inverter. Early AC-to-DC converters used an induction or synchronous AC motor direct-connected to a
