Latest Patents

Philip J Fitz 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 with respect to the system voltage and/or adjusting the voltage values of the threshold levels. Additionally, it senses sudden and drastic changes in system voltage levels, using this information to alter the amplitude of the reference signal. This adjustment reduces the difference between the converter's multilevel voltage and the system voltage, thereby minimizing stress on the GTOs during faults.
