PROBLEM TO BE SOLVED: To provide a high power circuit which can prevent the damage or the performance deterioration of a device being the target of voltage application by shortening the rise time of power voltage at power ON. SOLUTION: This power circuit has a voltage detecting circuit which detects power voltage and a PWM control circuit which controls the above detected output voltage to be constant by adjusting the pulse width of the row of output pulses, according to the detected voltage, and outputs the row of initial pulses of fixed pulse width for raising the power voltage within a specified time at power ON.
