Abstract: The present technology relates to a driving circuit and a driving method, in which power loss at the time of switching an FET (Field Effect Transistor) can be reduced with a simple circuit configuration. A coil constitutes a resonance circuit together with an input capacitance at a gate of the FET. A switch (regeneration switch) turns on or off current flowing in the coil. A DC power source is a power source to replenish the resonance circuit with electric charge and is connected to the gate of the FET. A switch (replenish switch) turns on or off connection between the DC power source and the gate of the FET. The present technology is applicable to, for example, a power source that outputs AC voltage and current by switching operation.
