MOTOR DRIVING CIRCUIT

摘要

A motor driving circuit is provided. The motor driving circuit includes an else inverter and a self inverter. The else inverter includes an else-inverter rectifier and an else-inverter driving circuit. The self inverter includes a self-inverter driving circuit and a soft-start protection circuit. The soft-start protection circuit includes a first and a second protection diodes, a self-inverter capacitor and a self-inverter soft-start circuit. The first protection diode is electrically connected to a first else-inverter-rectifier output and a first self-inverter-driving-circuit input. The second protection diode is electrically connected to a second else-inverter-rectifier output and a second self-inverter-driving-circuit output. The self-inverter soft-start circuit and the self-inverter capacitor are connected in series between a first cathode and a second anode of the first and the second protection diodes.
