Abstract: In an inverter circuit, more particularly in a single-phase inverter, soft switching is performed with a simple configuration to prevent switching loss of a switching element. A resonance circuit is configured by a resonant capacitor provided on the power supply side of a bridge circuit constituting a single phase inverter, a resonant inductor provided on the output side of the bridge circuit, and the bridge circuit. A resonance current passing through the resonance circuit allows zero voltage switching (ZVS) and zero current switching (ZCS) to be implemented at the rising time of main switching elements constituting the bridge circuit, and the zero voltage switching is implemented by means of zero voltage of the resonant capacitor at the falling time of the main switching elements constituting the bridge circuit.

Abstract: A phase of the pulse control signal upon restarting is synchronized with the phase of the pulse control signal upon suspending, thereby suppressing fluctuations of output voltage in each phase of the inverter upon restarting and further suppressing fluctuations of voltage supplied to the load. Upon supplying DC power to a plasma generator, when arc discharge occurs in the plasma generator, supplying of the DC power is suspended to reduce damage on the electrodes and substrate, and further upon extinguishing of the arc discharge, supplying of the DC power is restarted. In suspending and resuming the DC output, the current flowing in the chopper upon suspending is held in the form of circulating current, and upon restarting the inverter, this circulating current is supplied to the load. Accordingly, it is possible to reduce a delay in supplying the DC power to the load, upon resuming the DC output.

Abstract: Intermittent short-circuit control is performed in the ignition mode, thereby allowing short-circuit current to flow in the current source step-down type chopper. Energy of the short-circuit current is temporarily accumulated in the inductor provided in the current source step-down type chopper. The accumulated energy boosts the output voltage from the direct current power supply device during the period until the next short circuiting, via the current, the multiphase inverter, and the rectifier. The voltage boosting operation where accumulation of the current energy by short circuiting and boosting of the output voltage by conduction are repeated, controls an increase of the output voltage which is applied to the plasma generator.
