Title:
AC VOLTAGE CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2009/139505
Kind Code:
A1
Abstract:
Provided is an AC voltage control device inserted between an AC power source and an induction load so as to adjust a load voltage of the induction load by a magnetic energy regenerative switch. The device reduces the voltage load on an inverse-conductive semiconductor switch and a capacitor in the magnetic energy regenerative switch and controls voltage supplied to the induction load by using a small advance amount of phase of a current supplied to the induction load.
