METHOD AND POWER CONVERTER FOR PREDICTIVE DISCONTINUOUS CHARGE MODE CONTROL

摘要

The present invention relates to method 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 comprises generating a pulsed control signal for switching the power stage by varying a pulse width of the pulsed control signal so that a square of the pulse width is a function of a voltage error control signal derived from a difference between a reference voltage and the output voltage. This is a predictive method of charge mode control. The method is for a modulation scheme that does not require compensation for the discontinuous conduction mode.
