| Abstract |
Self-commutated Flicker Compensator: SFC, which compensates a voltage flicker and reactive
power, is supposed to be of lower cost, smaller size, and higher efficiency. A SFC applying GTO can
achieve a high ability of flicker suppression, but it is of high cost and requires large space because of
many components, such as snubber circuit, anode reactors, and large gate power source. Consequently
we have developed the SFC applying Flat-packaged IGBT and achieved short-circuit protection
without fuses. The SFC of 12MVA has been operating in the arc furnace plant since August 2001. |
