Latest Patents

Among his latest patents, the "Ripple Rejection Filter" stands out. This invention is designed to remove the fundamental frequency of load voltage from control signals in closed-loop phase-controlled systems. It employs a low-pass filter connected in parallel with a firing point synchronized sample and hold and high-pass filter series combination. The output from these filters is combined to produce a resulting signal that effectively rejects ripple from the input signal. Another significant patent is the "Digital Phase Synchronizer." This method and apparatus facilitate digital phase synchronization to an AC power line. It includes an analog-to-digital conversion that provides a digital phase error signal, which is processed by an inverting proportional plus integral transfer function. This signal is then compared to a digital timer to determine the timing for the next analog-to-digital conversion.
