摘要： PROBLEM TO BE SOLVED: To protect a self-turn-off element from a large current change generated at turn-on without using an arm reactor, and to regenerate a snubber energy to a main circuit and reduce a snubber loss. SOLUTION: The power converter has a main switching circuit series-parallel connecting a plurality of main switches to a DC power supply and snubber circuits connected in parallel with each main switch. The power converter has also auxiliary resonance circuits using parts of the main switching circuit and parts of the snubber circuits to form one path. The auxiliary resonance circuit turns a current and a voltage between both ends of the main switch to zero by discharge in the auxiliary resonance circuit, and the snubber energy of the snubber circuit is regenerated by a resonance circuit. A voltage rise at the turn-on is avoided without using the arm reactor by turning the current and the voltage between both ends of the main switch to zero by discharging the auxiliary resonance circuit. The surge of a DC voltage at the turn-off by the arm reactor is reduced, and the capacitor capacity of the snubber circuit is decreased by reducing the effect of a voltage surge.
