Zusammenfassung:A circuit structure of a voltage type single-stage multi-input low-frequency link inverter with an external parallel-timesharing select switch is formed by connecting a plurality of input filters connected to ground and a common output low-frequency isolation voltage-transformation filter circuit through a multi-input single-output high-frequency inverter circuit. Each input end of the multi-input single-output high-frequency inverter circuit is connected to an output end of each of the input filters in a manner of one-to-one correspondence. An output end of the multi-output single-input high-frequency inverter circuit and the output low-frequency isolation voltage-transformation filter circuit are connected. The multi-input single-output high-frequency inverter circuit includes an external multi-path parallel-timesharing select four-quadrant power switch circuit and a bidirectional power flow single-input single-output high-frequency inverter circuit successively connected in cascade.
