Abstract
A system and method are provided for increasing and maintaining voltage. A transformer'"'"'s secondary windings are connected between the hot input line and the hot output line, and are not switched. The secondary windings may be in series for 220/230 Vrms, and in parallel for 120/127 Vrms. Alternatively, the transformer may be a single voltage type specifically for 230 V, 120 V, or any other voltage range. A microprocessor measures incoming voltage and controls an electronic switch on the primary windings side of the transformer to short circuit the primary windings when the transformer is not needed. When voltage boost is needed, the switch may be controlled to connect the primary windings to neutral. When the primary windings are switched to neutral, the secondary voltage adds to the incoming AC line voltage. There may be multiple taps on the primary windings selected by the microprocessor for providing differing boost levels at differing input voltage levels. The boosted voltage may be maintained at predetermined levels based upon the turns ratio of the transformer. There are several embodiments of electronic switches, including, but not limited to, a diode bridge circuit in conjunction with an IGBT device. Transformers with different current ratings and/or turns ratios may be removably connected with the system.
