Abstract

PURPOSE:To supply stable voltage to a load, and also to reduce the power consumption, by automatically switching voltage from a high tap and voltage from a low tap, which have been provided on the secondary winding of a transformer. CONSTITUTION:Outputs of both a high tap 19 for fetching voltage whose absolute value is high, provided on a secondary winding 18 of a transformer, and a low tap 20 for fetching voltage whose absolute value is low are rectified. Subsequently, a thyristor 9 is inserted into an output transmission line of a high tap rectifying circuit 8, and output voltage of the thyristor 9 is compared with output voltage of a constant-voltage circuit. In this case, when the voltage of the thyristor 9 has exceeded prescribed voltage, the thyristor 9 is turned off by an output of the circuit 10, and an output of a low tap rectifying circuit 21 is fetched by an output terminal 17. On the contrary, when the voltage of the thyristor 9 does not exceed the prescribed voltage, the thyristor 9 is turned on by the output of the circuit 10, and the output voltage of the thyristor 9 is fetched by the terminal 17.
