COMPENSATION FREE MODULATION FOR POWER CONVERTERS

摘要

A method is provided for controlling a power stage of a power converter configured to generate an output voltage from an input voltage according to a control law controlling a switchable power stage. The method includes generating a pulsed control signal for switching the power stage and translating the pulsed control signal in phase relative to a constant frequency clock signal. The pulse is translated forward to increase charge in a cycle. The pulse is translated backward to decrease charge in a cycle. Thus, this method of charge control does not require compensation.
