Abstract
An electronic apparatus is provided which includes switching elements, resonance suppression resistors which have first ends connected to control terminals of the switching elements and second ends having a common connection, an on-drive circuit which has an on-drive resistor and is connected to a drive power circuit, and which is supplied with voltage from the drive power circuit and applies electric charge to the control terminals of the switching elements via the on-drive resistor to turn on the switching elements, and an off-drive circuit which has an off-drive resistor and releases electric charge from the control terminals of the switching elements via the off-drive resistor to turn off the switching elements. A resistance of the off-drive resistor is set to be smaller than a resistance of the resonance suppression resistors. The off-drive circuit releases electric charge from the control terminals of the switching elements not via the resonance suppression resistors.
