MOTOR DRIVER AND MOTOR DRIVING SYSTEM

WIPO Patent Application WO/2024/092409

A1

A motor driver and a motor driving system are disclosed. The motor driver (10, 20) includes a rectifier circuit (210), a DC link circuit (220), and an inverter circuit (230). The DC link circuit (220) is connected between the rectifier circuit (210) and the inverter circuit (230). The DC link circuit (220) includes a capacitor (C1), a seventh switch device (T1-T7), a freewheeling diode, and an inductor (L1). A first end and a second end of the capacitor (C1) are respectively connected to a positive output terminal and a negative output terminal of the rectifier circuit (210). A collector of the seventh switch device (T1-T7) is connected to the first end of the capacitor (C1), an emitter of the seventh switch device (T1-T7) is connected to a negative electrode of the freewheeling diode, and a positive electrode of the freewheeling diode is connected to the second end of the capacitor (C1). A first end of the inductor (L1) is connected to a midpoint between the seventh switch device (T1-T7) and the freewheeling diode, and a second end of the inductor (L1) and the positive electrode of the freewheeling diode are used as two terminals for connection to an energy storage element.
