It has a positive power supply for forward bias, a negative power supply for backward bias, a first bias circuit that outputs the positive- or negative-power-supply voltage according to gate driver signal S, a capacitor that is charged by the negative-power-supply voltage when the first bias circuit outputs the negative-power-supply voltage, and a second bias circuit that supplies the gate of the semiconductor device with the positive- or negative-power-supply voltage according to gate driver signal S. Only in an early stage of a transition period during which the semiconductor device is turned on, the second bias circuit supplies the gate of the semiconductor device, instead of the positive-power-supply voltage, with a voltage boosted by adding the charged voltage of the capacitor onto the positive-power-supply voltage outputted from the first bias circuit."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Gate driver circuit and power conversion apparatus using same","description":"A gate driver circuit capable of quickly driving a semiconductor device without erroneous ignitions.
