PROBLEM TO BE SOLVED: To provide a system linking inverter that converts input power for supplying so that the input power is suited to a load or a power distribution system. SOLUTION: A primary side is composed by an inverter circuit for converting a DC power supply and DC to high frequencies. The inverter circuit consists of primary winding 5a of a high-frequency transformer 5, a current-limiting coil 6, a resonance capacitor 4, and a switching element 3. The collector emitter voltage of the switching element 3 is detected by a switching element voltage detection means 16, and at the same time the ON time of the switching element 3 is limited when the collector emitter voltage exceeds a threshold. |
