The working principle and circuit structure of a pure sine wave inverter power supply with single-phase voltage amplitude continuously adjustable based on SM2001 are proposed. The experimental waveform and conclusion of the inverter power supply system are given, and the experimental results show the correctness and feasibility of the circuit design. This system can be widely used in power supplies required by various semiconductor test benches and various equipment that require power supply output voltage to be adjustable sine wave.
