Latest Patents

Yuji Hashiya holds a patent for a "Fault detector apparatus having serial fault-detection signal path." This apparatus is designed for power converters that utilize multiple Gate Turn-Off thyristors (GTOs) operating at a predetermined potential. The invention includes a first fault-detecting circuit that generates a fault signal when one of the GTOs malfunctions. Additionally, a second fault-detecting circuit serves a similar purpose for another GTO. The system employs a photocoupler to transmit a DC-isolated optical signal corresponding to the first fault signal. Furthermore, an optical fiber system transmits a DC-isolated output signal, which represents the logical sum of the optical signal and the second fault signal to external circuits.
