Abstract

There is provided a power supply circuit (14) including a power converting unit (20), a control unit (21), and a power supply unit for control (22). The power converting unit (20) converts a conduction angle controlled alternating-current voltage supplied via a power supply path (25) so as to be supplied to a load (12). The control unit (21) detects a conduction angle of the alternating-current voltage and controls conversion of a voltage by the power converting unit (20) according to the detected conduction angle. The power supply unit for control (22) is electrically connected to the power supply path (25) and converts the alternating-current voltage so as to be supplied to the control unit (21).
