Abstract
Official abstract text for this publication.
A pulse width modulation (PWM) power conversion system has improved efficiency over a wide operating input voltage and load range. Being able to measure relative efficiency of an analog PWM system allows enhanced control while maintaining the benefits of analog control. An analog low pass filter produces an average value of the PWM pulse train, then this analog average value is converted into digital values with an analog-to-digital converter and stored so that relative efficiencies of the PWM power conversion system may be compared for various combinations of operating parameters.
First claim
Opening claim text (preview).
What is claimed is: 1. A switch-mode power supply (SMPS), comprising: at least one power switch coupled to a voltage source; a power inductor coupled to the at least one power switch; a filter capacitor coupled to a load side of the power inductor that provides a regulated voltage output of the SMPS; at least one driver coupled to the at least one power switch; a pulse width modulation (PWM) generator having at least one output coupled to and controlling the at least one d…
