Latest Patents

One of Vlad Anghel's latest patents is titled "Fault protection testing in a high-power switching system." This invention discloses a power system that includes a gate driver equipped with test circuitry to detect faults. The system is designed to test the fault detection circuitry to confirm its effectiveness in identifying faults. Various methods and circuit implementations are presented to assess the system's fault detection capabilities. The testing process may involve different configurations and protocols to identify components responsible for failures, which may include elements within the gate driver or those externally coupled to it. Notably, the approach does not significantly increase complexity, as a test input can be communicated from a low voltage side to a high voltage side over a shared communication channel.

Another significant patent by Anghel is the "Gate driver." This invention pertains to a gate driver designed to control a high-power switching device. The gate driver features a multifunction pin that allows it to be controlled by a multifunction signal, enabling it to perform various functions. For instance, the level of the multifunction signal at the multifunction pin can enable or disable the output of the gate driver. Additionally, holding the multifunction signal at a specific level for a period while the gate driver is in a fault state can reset its state. Pulsing the multifunction signal multiple times can also activate a test of the gate driver's fault detection capabilities. By utilizing a single pin for control, this design simplifies circuit complexity for communication between a controller and the gate driver, ultimately reducing costs and enhancing reliability.
