The invention provides a six-phase motor driver topology and a control algorithm. The six-phase motor driver topology comprises a six-phase motor, a driver and a controller, wherein the controller controls a working state of the six-phase motor through the driver; the driver comprises an inverter; the inverter adopts a two-stage six-phase H-shaped bridge type structure; the two-stage six-phase H-shaped bridge type structure is formed by two single-stage three-phase H-shaped bridge type structures which are connected in series; and each of the single-stage three-phase H-shaped bridge type structures is formed by three single-stage single-phase H-shaped bridge type structures which are connected in parallel. According to the control algorithm, space vector decoupling is realized through 6/2 transformation, and a six-phase space voltage vector is decoupled into a two-phase voltage vector under a dq coordinate system, so that independent control of excitation and torque of the six-phase motor is realized. The six-phase motor driver topology has the beneficial effects that the voltage resistance levels of power switch tubes of bridge arms can be lowered; harmonic waves can be injected into a motor stator phase winding through the topology; and the topology can still run under the condition that at least two phases of motor windings are not damaged.
