PROBLEM TO BE SOLVED: To provide a high frequency inverter which is able to share an inductance for restraining high frequency noise and an impedance element for reducing the charging current of a smoothing capacitor for restraining the harmonics, thereby simplifying its circuit formation. SOLUTION: This device is provided with a capacitor C1 for noise prevention parallel-connected to an AC power source 1, a rectifying means 4 parallel- connected to the capacitor and rectifying alternating current inputted, a capacitor C2 for smoothing, an inductive impedance element L1 which is inserted between the capacitor C2 for smoothing and the capacitor C1 for noise prevention, and is formed so as to be capable of restraining the charging rush current of the capacitor for smoothing by retraining outflow of a high-frequency component to commercial AC power supply side, in cooperation with the capacitor for noise prevention, a high-frequency generating circuit which converts alternating current into high-frequency alternating current, and a load circuit LC operating at high frequencies. |
