PURPOSE: A voltage stabilization control circuit of a direct current power apparatus is provided to output a stable voltage in a case where one output voltage is affected by a variation of the other output voltage. CONSTITUTION: A voltage stabilization control circuit of a direct current power apparatus comprises first and second voltage division resistors(R1,R2), a sense condenser(Cs) and a comparator(41). The first and second voltage division resistors(R1,R2) senses a variation of an output voltage(Vo), and the sense condenser(Cs) interrupts a direct current. The sense condenser(Cs) reflects a variation of an input alternating current voltage(Vin) to a sense voltage(Vs) by the first and second voltage division resistors(R1,R2). The comparator(41) compares a voltage obtained by the resistors(R1,R2) and the condenser(Cs) with a reference voltage(Vref) to perform a voltage stabilization control by use of a control output signal(Vc).
