HIGH-VOLTAGE DRIVER SWITCH SYSTEM AND SWITCHING METHOD

The invention discloses a high-voltage driver switch system and switching method. The system comprises a main control chip module (30) and an energy storage capacitor (C1) connected to a battery pack (10), a drive circuit module (80), a pre-charging circuit and a charging circuit for charging the energy storage capacitor (C1). The pre-charging circuit is connected to the main control chip module (30) and has a current limiting resistor (R1), so as to pre-charge the energy storage capacitor (CI) under the control of the main control chip module (30). The charging circuit is connected to the main control chip module (30) and has an electronic switching module (20) which comprises two ends connected respectively to the battery pack (10) and the energy storage capacitor (CI), the battery pack (10) charges the energy storage capacitor (CI) when switched-on. The invention reduces the instantaneous start-up current and avoids a high current impact caused by charging the energy storage capacitor (CI) by the battery pack (10) directly.
