Abstract

A switched power converter includes a power stage for generating an output voltage according to a switching signal and an input voltage via a switching element. The switching signal is generated by a variable timing generator which is controlled by a compensator. The pulses of the switching signal are generated on a “need to have basis”. Hence, theses pulses may be generated independently of a PWM period. The pulses can be generated such that switching losses are minimized. A switching pattern can be matched to the load current pattern. Thus, the behavior of the compensator can be synchronized to a regular pattern of the load current. A high resolution variable timing generator may be employed.
