Title:
DC PULSED POWER SUPPLY DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/152946
Kind Code:
A1
Abstract:
A DC pulsed power supply device (1) includes: a DC power supply (10); a pulsing unit (20A) that generates a pulsed output using a step-up chopper connected to the DC power supply; and a recovery unit (30). The recovery unit recovers, to the DC power supply, the voltage portion among a reactor voltage (VDCL) of a DC reactor (21A) in the step-up chopper exceeding a set voltage. Thus, the voltage of the step-up chopper is clamped to a prescribed voltage to suppress excessive voltage increases. Moreover, resistor energy consumption is resolved and the efficiency of supplying power to a load is increased by recovery to the DC power supply.
