Feedforward pulse-width modulator for boost DC-DC power converters
Abstract
The authors describe a novel pulse-width modulator with feedforward compensation of input voltage disturbances in boost DC-DC switched mode power converters. The modulator transforms an open-loop boost converter into a linear DC voltage amplifier. It is suitable for simple integrated-circuit implementation using the same building blocks as existing PWM (pulsed width modulation) controllers for switched mode power supplies.
