Latest Patents
One of Charles H Shin's notable inventions is the "Zero voltage crossover detector for polyphase systems." This invention finds application primarily in three-phase power systems that have A, B, and C voltage phases. The invention includes a first voltage measurement device coupled between the A phase input and the B phase input, which provides a first measured voltage output. Additionally, a second voltage measurement device is coupled between the A phase input and the C phase input, yielding a second measured voltage output. A comparator is also included, with a first input connected to the first output of the first voltage measurement device and a second input connected to the second output of the second voltage measurement device. This comparator generates a signal when the first measured voltage is equal to and opposite in polarity from the second measured voltage, indicating that a zero crossover event has occurred with the A phase. Charles holds 1 patent for this innovative technology.
