Latest Patents

Ellison's latest patents focus on measuring output current in a buck switched-mode power supply (SMPS). His innovative approach involves a sample and hold circuit that captures the current flowing through an inductor at the midpoint of the low side switch ON during the pulse width modulation (PWM) period. This method allows for the determination of the 'average' or 'DC output' current of the SMPS. By utilizing a constant current source and sink, he effectively charges and discharges a timing capacitor, with its voltage monitored by a high-speed voltage comparator to ensure precise sample timing.
