Abstract

See full text

The technology of this application relates to a drive circuit with an energy recovery function, including a control circuit, an energy recovery drive circuit, a switch circuit, and a direct current power supply. The control circuit is configured to control an energy storage capacitor in the energy recovery drive circuit to charge a junction capacitor of the switch circuit at a first moment, and enable the direct current power supply to charge the junction capacitor of the switch circuit through the energy recovery drive circuit at a second moment, so that the switch circuit is switched on. The control circuit is further configured to control the junction capacitor of the switch circuit to charge the energy storage capacitor in the energy recovery drive circuit at a third moment, and enable the junction capacitor of the switch circuit to discharge to a ground through the energy recovery drive circuit at a fourth moment, so that the switch circuit is switched off.
