Abstract
Various embodiments relate to a converter controller configured to control a resonant converter, including: an integrator configured to receive a current measurement signal from a current measurement circuit in the resonant converter and to produce a capacitor voltage signal indicative of the voltage at the resonant capacitor; a control logic configured to produce a high side driver signal, a low side driver signal, a symmetry error signal based upon the capacitor voltage signal and the current measurement signal; and a symmetry controller configured to produce a symmetry correction signal based upon the symmetry error signal, wherein the symmetry error signal is input into the integrator to control the duty cycle of the high side driver signal and the low side driver signal, wherein the high side driver signal and the low side driver signal control the operation of the resonant converter.
