ABSTRACT:
A phase delay control for a power converter operates with a phase locked loop and current sense feedback to provide improved control stability and dynamic output range. The phase lock loop includes a voltage controlled oscillator that is controlled based on an error signal derived from a phase of the power converter output. The error signal applied to the voltage controlled oscillator produces a shift in switching frequency for the converter to drive the error to zero. The power converter includes an LCC resonant circuit to manipulate resonant electrical energy to improve switching speed and power density.
