A drive circuit includes a control circuit configured to output a polarity signal for controlling ON/OFF of a driving switch, a pulse transformer, electrically connected to the control circuit, configured to transmit the polarity signal, and a discharge circuit, electrically connected to the pulse transformer and a gate terminal of the driving switch, configured to discharge an electric charge accumulated in the gate terminal based on the polarity signal. When the polarity signal...
More DescriptionA drive circuit includes a control circuit configured to output a polarity signal for controlling ON/OFF of a driving switch, a pulse transformer, electrically connected to the control circuit, configured to transmit the polarity signal, and a discharge circuit, electrically connected to the pulse transformer and a gate terminal of the driving switch, configured to discharge an electric charge accumulated in the gate terminal based on the polarity signal. When the polarity signal having a first polarity is applied to the gate terminal through the pulse transformer, the driving switch is switched to and maintained in an ON state by accumulating the electric charge in the gate terminal. When the polarity signal having a second polarity different from the first polarity is applied to the discharge circuit through the pulse transformer, the driving switch is switched to an OFF state by discharging the electric charge by the discharge circuit.
