Latest Patents

Matsui's latest patents include a "Safety Enhanced Transformer Circuit." This invention features a neon transformer with secondary windings connected through a voltage detection circuit to a ground terminal. A resistive element is shunted with the voltage detection circuit, which may include a Zener diode and a light-emitting element of a photocoupler. This design allows for the detection of ground faults, ensuring that the supply of alternating current (AC) power is interrupted when necessary.

Another significant patent is the "Protection Circuit for Tap-Grounded Leakage Transformer." This invention detects induced voltages from two tertiary coils magnetically coupled with two secondary coils. The detected voltages are compared with a reference voltage, and when a grounding issue occurs, the corresponding comparator output reduces to zero volts, activating a relay to shut off the AC power supply.
