Abstract: A motor driver with an inverter circuit having a first to a third DC/AC conversion branch in parallel between output terminals of a direct current link circuit; and a filter circuit with a three-phase inductor. Head terminals of the inductor are connected to midpoints of the branches and tail terminals output three phase voltages. A compensation circuit includes a coupling inductor with a center tap and a solid-state circuit breaker. The coupling inductor is coupled to the inductor. A moving point of the solid-state circuit breaker includes a first and a second switch contact. The first switch contact is connected to a head terminal of the inductor, the second switch contact is connected to the center tap of the inductor, the solid-state circuit breaker is connected to a midpoint of a half-bridge branch, and a tail terminal of the inductor is connected to a midpoint of a capacitor branch.

Abstract: Some embodiments of the teachings herein include a motor driver with an input end connected to a three-phase power grid, an output end connected to a motor, a rectifying circuit, a DC link circuit; and an inverter circuit. The inverter circuit has three DC/AC conversion branch circuits connected in parallel between positive and negative output ends of the DC link circuit and each conversion branch circuits has six switching devices. The rectifying circuit comprises a rectifier bridge, a first half bridge, three switches, and an inductor. When the motor is operating in a braking regeneration mode, regenerated energy generated during braking of the motor is fed back to a power grid.
