An on load tap changer type constant AC voltage device can change the output voltage for supplying load due to tap changer combined from multiple semiconductor connections of primary transformer auxiliary winding when the input voltage from AC power source is transformed through the transformer to supply the load. It features that by detecting the variance of load output voltage caused by the input voltage variance one tap changer control device can change the multiple taps of auxiliary winding in non-transient state into proper tape that modifies the voltage variance, and a serial transformer wired to the output of primary transformer that increments or decrements the output voltage depending the modified voltage, and a current limiting reactance that depresses the loop current, which is caused by the tap changer operation of the auxiliary winding, flowed in auxiliary winding.
