Abstract

The invention discloses a recoil voltage protection device. The recoil voltage protection device comprises a DC bus detector, a protection loop switch and a protection loop load; the DC bus detector is respectively connected with the DC bus and the protection loop switch and is used for detecting the recoil voltage on the DC bus in real time and controlling the connection and disconnection of theprotection loop switch according to the detected recoil voltage; the protection loop switch is respectively connected with the DC bus and the protection loop load and is used for transmitting the recoil voltage on the DC bus to the protection loop load when the protection loop switch is switched on; and the protection loop load is used for releasing the recoil voltage transmitted from the protection loop switch. The invention further discloses a multi-channel servo motor drive control power supply system and a recoil voltage protection method. According to the invention, the voltage of the DCbus can be monitored in real time, the recoil voltage generated during braking and reversing of the servo motor is isolated and released through the recoil voltage protection loop, and a drive controlsystem and other electric parts on the DC bus can be protected.
