Abstract:
1. A gate driving circuit for driving switching element having a gate input capacitor comprising: a primary circuit; and a secondary circuit, wherein the primary circuit comprises: the first switching element and the second switching element are configured to charge the gate input capacitor, the third switching element is configured to discharge the gate input capacitor, when the first switching element and the second switching element are on, in the primary circuit, a first current flows through the first switching element and the second switching element, in the secondary circuit, a charge current generated based on the first current flows through the third unidirectional element, and when the third switching element is on, in the secondary circuit, a discharge current flows through the third switching element, in the primary circuit, a second current generated based on the discharge current flows through the first unidirectional element and the second unidirectional element.
