Abstract
The invention discloses a high-voltage driver switch system and switching method. The system includes a main control chip module and an energy storage capacitor connected with a battery pack, a drive circuit module, a pre-charge circuit and a charge circuit for charging the energy storage capacitor. The pre-charge circuit is connected with the main control chip module and has a current limit resistor, so as to pre-charge the energy storage capacitor under the control of the main control chip module. The charge circuit is connected with the main control chip module and has an electronic switch module which includes two ends connected respectively with the battery pack and the energy storage capacitor, the battery pack charges the energy storage capacitor when switched-on. The invention reduces the instantaneous start-up current and avoids a high current impact caused by charging the energy storage capacitor by the battery pack directly.
