ABSTRACT:
An apparatus for controlling output signals at an output locus of a power converting device has a rectifier coupled to receive an input signal and present a rectified input signal for switching connection with one of a first and a second network. The first network includes the rectifier. The second network includes part of the first network and the output locus. The networks establish a return current to the rectifier. The apparatus includes: (a) a current indicating unit coupled with the output locus for combining an extant output signal with a time-integrated signal to present a calculated current signal; and (b) a comparing unit coupled with the first network and the current indicating unit for receiving the return current. The comparing unit drives the switching connection when the calculated current signal and the return current have a predetermined relationship.
