Latest Patents

Yoon holds a patent for an apparatus designed to detect ground faults in ungrounded DC power supply systems. This invention involves a DC power supply connected by positive and negative lines to a load. The system selectively applies an AC voltage between a positive line and ground or between a negative line and ground. A current sensor, which includes an electrical coil surrounding the positive and negative lines, responds to significant alternating current in one of the lines when the AC voltage is applied. This mechanism effectively indicates a fault when a ground fault occurs.
