Latest Patents
Keith Abbott holds a patent for a "Control arrangement for a multilevel convertor." This invention employs an AC reference signal that is locked to the AC system frequency. It compares this signal with several DC threshold levels. The intersections of the reference signal and threshold levels trigger the firing and turning-off of Gate Turn-Off (GTO) thyristors within the converter. This process produces the desired multilevel voltage output. The invention also compensates for normal changes in system voltage by varying the phase relationship of the reference signal and the voltage values of the threshold levels. Additionally, it senses sudden and drastic changes in system voltage levels and adjusts the amplitude of the reference signal to reduce stress on the GTOs during faults.
