Method of controlling power regenerative equipment.

摘要

A method of controlling a power regenerative equipment: providing in sequence "on" timing signals to self-arc-extinguishing semiconductor devices in response to phase voltages of an AC power source, and overlapping two of the "on" timing signals corresponding to two adjacent ones of the phase voltages with each other during a period of time from a point that a potential difference between the two adjacent ones of the phase voltages is smaller than a predetermined value to a point that the potential difference is null. <IMAGE>
