Latest Patents

One of Hsia's latest patents is focused on fault protection testing in a high-power switching system. This innovation involves a power system that includes a gate driver configured with test circuitry to detect faults. The system is designed to test the fault detection circuitry to confirm its ability to identify faults effectively. Various methods and circuit implementations are disclosed to assess the system's fault detection capabilities. The testing process may involve different configurations and protocols to determine which components are likely responsible for a failure. Notably, the approach does not significantly add complexity, as a test input to initiate a test can be communicated from a low voltage side to a high voltage side over a shared communication channel.

Another significant patent by Hsia is related to a gate driver circuit. This electronic circuit receives an input signal and a signal corresponding to the current through a switch. It produces an output signal for controlling the switch based on the input signal. When the input signal is de-asserted, the gate driver circuit can turn the switch off at a normal turn-off rate if the current is below an overcurrent (OC) threshold. Conversely, if the current exceeds the OC threshold, the circuit turns off the switch at a slower OC turn-off rate.
