    摘要: A DC power source to supply DC power to a plasma generator is configured as a simple and small-sized device that forms high voltage for generating a plasma discharge. A step of passing a short-circuit current for extremely short time through the voltage source step-down chopper provided in the DC power source and accumulating energy in a reactor is performed repeatedly more than once, so as to discharge the energy accumulated in the reactor to the output capacitance and raise the output voltage sequentially, thereby boosting the voltage up to the ignition set voltage. The short-circuit current is formed by a switching element of a boosting circuit provided in the DC power source. Boosting the voltage at the output terminal by accumulating and discharging the short-circuit current is repeated to raise the voltage at the output terminal of the DC power source up to the ignition set voltage.

    摘要: 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.

    摘要: 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.

    摘要: In a voltage-type DC power supply provided with an inverter, current supply from the inverter to the load side is suppressed when arc is generated. DC output from the voltage-type DC power supply is suspended and resumed: upon suspending the DC output, the chopper is separated from the inverter, thereby suppressing excessive current to the load when arc is generated, allowing the arc to be extinguished at high speed, and holding the current passing through the chopper in the form of circulating current. Upon restarting the inverter, the circulating current being held is supplied to the load, thereby reducing a delay of supply of DC power to the load at the time of resuming the DC output from the voltage-type DC power supply.
