Title:
INJECTION MOLDING MACHINE AND POWER SOURCE REGENERATION CONVERTER
Document Type and Number:
WIPO Patent Application WO/2011/162246
Kind Code:
A1
Abstract:
The disclosed injection molding machine, which is provided with a power source regeneration converter (10) connected between an AC power source (20) and an inverter unit (30), is provided with: a power conversion unit (11) that converts in both directions between AC power and DC power; a DC voltage detection unit (15) that detects the DC voltage of a capacitor (14) that is between the inverter unit (30) and the power conversion unit (11); and an AC current control unit (16) that outputs to the power conversion unit (11) a control signal generated on the basis of the voltage difference between a predetermined voltage and the DC voltage that the DC voltage detection unit (11) detects, and controls the AC current that flows between the AC power source (20) and the power conversion unit (11).
