Abstract
A motor drive system includes a precharge circuit having an intelligent charging and discharging mechanism. In terms of charging, a delay circuit can be used to delay a timing for turning on the low-impedance path, a detection circuit can also detect a system status and a battery voltage, and perform a discharge process in a non-driving mode and when the battery voltage continues to decrease. In the discharge process, a variety of applications can be realized using driving mechanism of the motor drive system.
