Latest Patents
Hyunyoung Jung's latest patents include innovative designs for earth leakage circuit breakers. The first patent describes a device that incorporates a leakage current detection unit, which outputs a leakage current detection signal. This device features a conversion unit that provides the leakage current magnitude of a fundamental wave component, along with the ratios of a third harmonic component and the peak current values. The control unit compares these values with predetermined reference values to determine the presence of leakage currents in both alternating and direct current components, ultimately outputting a trip control signal when necessary.
The second patent also focuses on an earth leakage circuit breaker, which includes a current sensing unit that detects current in a circuit. This device utilizes a converter to identify both a fundamental wave component and a specific harmonic component from the sensed current. The controller then compares the harmonic component ratio with a threshold to determine if the current is abnormal, controlling the circuit cutoff based on this determination. The converter is designed to convert the sensed current from an analog signal into digital data and perform a Fourier transform to detect the necessary components.
