Self-excitation boost high-response high-torque driver capable of suppressing back electromotive force

A self-excitation boost high-response high-torque and counter electromotive force suppressing driver comprises a rectifier module A, a filter module B, a self-excitation boost control circuit, a driving inversion control circuit L and a control processing module. The driver drives the motor Q to operate; a power input VIN is input into the driver through the input port, and is processed by the rectifier module A and/or the filter module B to be transmitted to the self-excitation boost control circuit; according to the invention, the bus voltage in the driver is boosted to a reasonable voltage that the motor can bear, and a new bus voltage in the driver is obtained, so that the torque of high-speed output in the motor is improved, the speed of the motor is improved, the response of the motor is improved, and the efficiency of the system is improved. The back electromotive force generated in the operation of the motor is effectively suppressed or prevented from being fed back to the bus of the power supply, the
