ELECTRIC TOOL AND METHOD OF DRIVING ELECTRIC TOOL

When a work stops without driving after a voltage across a capacitor circuit reaches a target boost voltage, a micro-computer switches an FET through a driver circuit. As a result, the voltage charged in the capacitor circuit is charged in a secondary battery through the FET, an inductance, and a pa...

Zusammenfassung:	When a work stops without driving after a voltage across a capacitor circuit reaches a target boost voltage, a micro-computer switches an FET through a driver circuit. As a result, the voltage charged in the capacitor circuit is charged in a secondary battery through the FET, an inductance, and a parasitic diode of an FET.
