PURPOSE:To provide a power supply circuit which generates an AC voltage and a DC voltage from a DC voltage source, which is small in size and light in weight and, further, which is free from a voltage fluctuation. CONSTITUTION:A power supply circuit is composed of a DC voltage source such as a battery 4, a switching means 31 which converts the output of the DC voltage source into an AC voltage by a switching operation, a transformer 22 whose primary side receives the output of the switching means 31, a means 21 which supplies an AC voltage converted by the transformer 22 to a load 3, a rectifying circuit 28 which receives another secondary output and a voltage stabilizing means 29. |
