Abstract

PURPOSE:To simplify a controlling circuit by setting the ON time of the first switching element connected to the primary coil of a transformer and controlling the second switching element connected to the tertiary coil for feeding back the excessive current of the primary coil to the power source side in response to the load. CONSTITUTION:Reverse polarity primary coil n1 and tertiary coil n3 are provided at the primary side of a converter transformer 13, a transistor 14 is connected to the primary coil n1, and a transistor 42 is connected to the tertiary coil n3. The ON time of the transistor 14 is fixed corresponding to the maximum load time, and the voltage of the load 19 is controlled by controlling the current fed back to the power source 11 side from the tertiary coil n3 under the control of the ON time of the transistor 42. Thus, the arrangement of the controlling circuit can be simplified, and the controlling range can be increased.
