An AC power regulator is provided which employs both resistance and phase regulation. Between zero and half power, resistance regulation is employed in series with a unidirectional conducting device such as a diode. Between half power and full power, resistance regulation is employed in parallel with the diode which acts as a phase regulator. Accordingly, heat is generated in the rheostat only during one-half cycle of the load current. The maximum heat to be dissipated by the regulator is then equal to half the maximum heat to be dissipated by a regulator without phase regulation or diode.
