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.
