Title: Michael Thomas Engelhardt: Innovator in Power Supply Technology
Introduction
Michael Thomas Engelhardt is a notable inventor based in Sunnyvale, CA. He holds a total of 8 patents that showcase his contributions to the field of power supply technology. Engelhardt's work primarily focuses on enhancing the efficiency and performance of switch mode power supplies.
Latest Patents
One of Engelhardt's latest patents is titled "Spread spectrum for switch mode power supplies." This invention involves utilizing a switching signal to control power switches within a switch mode power supply. The controller generates a switching signal that reduces peak spectral noise by varying the instantaneous switching frequency at a constant slew rate. This frequency modulation is achieved through a random bit stream, which is integrated and filtered to maintain stability.
Another significant patent is "Predictive ripple-cancelling signal into error amplifier of switch mode power supply." This innovation predicts ripple in the feedback voltage of a switching converter based on recent switching cycles. By filtering out the DC portion of the feedback voltage and adding it to a fixed reference voltage, Engelhardt's design effectively cancels out ripple components, resulting in a more stable control voltage and improved response to transients.
