摘要： In a DC pulse power supply device according to the present invention, at the time of starting pulsing operation, the duty of the pulsing operation of a chopper circuit is controlled, a switching element is set to an ON state, and the pulse width at which the DC reactor is in an energized state is made variable over the period until the capacitor voltage is charged to a sufficient voltage to reset the magnetic saturation of the DC reactor. Gradually increasing the pulse width suppresses the degree of increase in the DC reactor current, and suppresses the DC reactor current below the magnetic saturazion level. As a result, the magnetic saturation of the DC reactor is suppressed at the time of starting pulsing operation.

摘要： In the present invention, when a DC reactor is in a magnetically saturated state, the on/off operations of a switching element are suspended and the switching element is set to an off state for a predetermined period of time, thereby resetting the magnetic saturation of the DC reactor and maintaining the supply of power to a load. After resetting the magnetic saturation, the pulse output of the normal pulse mode is restarted.

摘要： There is provided a radio frequency power source device configured to change a voltage ratio between two output end voltages, by switching a connection state of a voltage divider that divides the radio frequency voltage, in such a manner that the radio frequency voltage is divided into voltage outputs in antiphase with each other with respect to ground potential, and high voltage and low voltage are delivered in switching manner. Switching of the connection state in the voltage divider enables selective delivery of voltage having different values, high voltage or low voltage, and by selecting and delivering high voltage for the time high voltage is required, reduction of the voltage output from the radio frequency output circuit is prevented.

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： A DC pulse power supply device (1) includes: a DC power supply (10); a pulsing unit (20A) that generates a pulse output using a step-up chopper circuit connected to the DC power supply; and a regeneration unit (30). The regeneration unit regenerates, to the DC power supply, the voltage component among a reactor voltage (VDCL) of a DC reactor (21A) in the step-up chopper circuit exceeding a set voltage. Thus, the voltage of the step-up chopper circuit is clamped to a prescribed voltage to suppress excessive voltage increases. Moreover, resistor energy consumption is eliminated and the efficiency of supplying power to a load is boosted by regeneration to the DC power supply.

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.

摘要： This DC-pulse power supply device is provided with: a DC power supply; a pulse unit (20) for generating a pulse output using a step-up chopper circuit connected to the DC power supply; and a voltage superimposing unit (30A, 30B) connected to a DC reactor of the step-up chopper circuit. The voltage superimposing unit (30A, 30B) superimposes an amount (Vc, VDCL2) corresponding to a superimposed voltage on the output voltage of the step-up chopper circuit. The pulse unit (20) outputs, in a pulse form, the output voltage (Vo) on which the amount (Vc, VDCL2) corresponding to the superimposed voltage is superimposed by the voltage superimposing unit (30A, 30B). The amount corresponding to the superimposed voltage is superimposed on the pulse output of the step-up chopper circuit, thereby raising the output voltage of the pulse output of the step-up chopper circuit.

摘要： This DC pulse power supply device includes: a DC power supply unit (10); and a pulsing unit (20) that generates a pulse output using a step-up chopper circuit connected to the DC power supply unit. A clamp voltage unit (30) has an output end that is connected to a connection point (s) between a switching element (22) and a DC reactor (21), and applies a clamp voltage (VC) to one end of the switching element (22). During an off period (Toff) of the step-up chopper circuit, the voltage at both ends of the switching element is clamped so as to prevent damage to the switching element, suppress output voltage fluctuations resulting from load current fluctuations, and suppress power loss caused by a load current and a discharge current flowing through a resistor.

摘要： This DC pulse power supply device comprises a voltage clamper including a capacitor that is connected in parallel to a DC reactor in a chopper circuit provided in a pulsing unit in order to suppress increases in the surge voltage resulting from the leakage inductance of the DC reactor. During the start-up of pulsing operation, which is the initial stage of the pulse mode, the frequency of the pulsing operation of the chopper circuit is controlled over the period until the capacitor voltage is charged to a sufficient voltage to reset the magnetic saturation of the DC reactor.
