PROBLEM TO BE SOLVED: To operate a power supply if a voltage input to a current resonant power supply fluctuates, without producing off-resonance.SOLUTION: The power supply includes: an inductor connected between the a first and a second switching element; a capacitor connected between the inductor and second switching means; and a current detector circuit connected to the capacitor, to control the operation of the first and second switching elements, on the basis of an input-side current of the AC voltage of the first switching element and the detection result of the current detector circuit.SELECTED DRAWING: Figure 2 |
