Title:
RECTANGULAR WAVE POWER SUPPLY REGENERATION DEVICE
Document Type and Number:
Japanese Patent JP2017005801
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a rectangular wave power supply regeneration device capable of suppressing a spike current during commutation with a simple circuit and control.SOLUTION: A rectangular wave power supply regeneration device includes a power conversion circuit for converting a DC voltage, inputted from an inverter device, into a three-phase rectangular AC voltage, a current detection circuit, an AC three-phase detection circuit, and a control section for outputting a rectangular wave three-phase AC voltage via the reactor. The control section detects a reference value based on a DC current detected by the current detection circuit, and the peak value of a spike current generated by switching of a switching element, sets the phase shift amount so that the deviation amount or the value or ratio thereof is reduced, and drives the switching element of the power conversion circuit to shift the phase thus outputting the rectangular wave three-phase AC voltage.SELECTED DRAWING: Figure 1
