Latest Patents

Two of his latest patents exemplify his innovative contributions to the field. The first is a "Commutation Controller" devised for a switched reluctance machine. This controller utilizes separate timer circuits for firing signals in both motoring and generating modes. Each timer consists of a ramp generator and comparators that define the ON- and OFF-angle based on preset thresholds. A multiplexer selects the appropriate timing output, enabling smooth transitions between operational modes without timing errors.

The second patent, a "Demodulator for a Pulse Width Modulated Signal and Method," introduces a unique approach to accurately determine the duty cycle of pulse width modulated (PWM) signals. This demodulator features a counter that counts in opposite directions depending on the signal state. Clocked by an output from a frequency multiplier, it allows for the duty ratio computation, irrespective of the PWM signal frequency.
