Latest Patents

One of his latest patents is a method of identifying a short-circuit like event in a circuit breaker. This method involves sampling the incoming current to determine the maximum value of the slope of the current curve. It includes sampling the incoming current again before it reaches a predetermined short-circuit threshold value. By determining that the slope of the incoming current has changed, the method can identify a short-circuit like event without it being a real short-circuit event.

Another notable patent is for a power converter apparatus and a method of modulating it. This invention provides a power converter apparatus that converts alternating current (AC) power input to direct current (DC) power output. The apparatus consists of multiple single-phase power converting circuits arranged in parallel, enhancing the efficiency of power conversion.
