regenerative motor end surge voltage suppression device, the motor drive system, and the regenerative type motor end surge voltage suppression method

摘要

PROBLEM TO BE SOLVED: To provide a regenerative motor end surge voltage suppression apparatus capable of suppressing erroneous detection of an electric current by regenerating energy based on a surge voltage for high power use efficiency while suppressing a surge voltage, and to provide a motor drive system and surge voltage regenerative method.;SOLUTION: The regenerative motor end surge voltage suppression apparatus includes a rectifier with an input side connected to an input terminal of a motor that outputs a voltage including a high frequency through a cable by making an inverter device convert a DC voltage input into a DC input node to an AC voltage, and an I/O insulated DC-DC converter with an input side connected to a rectification output of the rectifier through a capacitor and with an output side connected to a DC input node of the inverter device.;COPYRIGHT: (C)2013,JPO&INPIT
