PURPOSE:To ensure control even to the input voltage which has an asymmetric change to the output voltage by means of an adjusting transformer of small capacity and a semiconductor switch circuit, by providing a series transformer which delivers the input voltage to an input terminal after boosting or reduction of voltage. CONSTITUTION:When the input voltage Vin has a 10% minus to the output voltage, thyristor switches 10 and 13 are turned on to set the compensation voltage VC1+VC2 at 10% (5%+5%) output voltage Vout. Then the voltage Vin is raised by 10% to compensate the voltage Vout. If the voltage Vin has a 5% minus to the voltage Vout, the switches 10 and 12 or 11 and 13 are turned on to set the voltage VC1+VC2 is set at 5% (5%+0%) voltage Vout. Then the Vin is raised 5% to compensate the Vout. When the Vin is equal to Vout, the thyristor switches 11 and 12 are turned on. Then the VC1+VC2 is set at 0, and the Vin is delivered at it is. |
