Abstract: PROBLEM TO BE SOLVED: To suppress power consumed in a power factor improving circuit, when power saving operation is performed, and besides to suppress power consumed in an apparatus, by short-circuiting a power factor improving circuit by a change-over circuit when the power saving operation is performed. SOLUTION: If a power saving control signal P1 is received from a host system 6, for example, the voltage of a secondary output V1 is lowered to the voltage of an output V2 through a secondary control circuit 5, and operation is transferred to power saving operation. The output voltage of a power supplying winding N1 lowers to a level lower than a voltage set by a voltage regulation diode ZD2, a change-over device Tr2 operates via a resistor R2 and a voltage regulation diode ZD1, and power is supplied from a driving auxiliary winding N2 to a primary control circuit 3. Accordingly, a detecting device Tr1 does not operate by the function of a diode D2 and the voltage regulation diode ZD2. A relay RL1 stops its operation, the contact of the relay RL1 is short-circuited, and a power factor improving circuit 1 is short-circuited.  When power saving operation is performed, power consumption in a capacitor C3, the diode D2, a resistor R1 and a detecting circuit 9 can be suppressed.
