Abstract
A voltage detecting apparatus detects a detected AC voltage generated in a detected object, and includes a detection electrode that is disposed facing the detected object, a detection unit that operates on a floating power supply generated with a voltage of a reference voltage unit as a reference and outputs a detection signal, and a standard signal outputting unit that outputs a standard signal to the reference voltage unit. The voltage detecting apparatus also includes an insulating unit that inputs the detection signal and outputs an insulated detection signal, a feedback control unit that amplifies the insulated detection signal, and a signal extracting unit that amplifies the insulated detection and outputs a signal component as an output signal.
