Abstract
Switch conductance regulation is used in favor over dynamic off-time modulation in resonant SC DC-DC converters due to its smaller output voltage ripple and operation at a constant frequency. However, at light load the resonant oscillations are significantly damped because of the increased on resistance Rdson of the power switches. A modeling approach is presented and experimentally verified showing that under these conditions it is beneficial to scale both Rdson and the switching frequency fswitch to further reduce switching losses while still maintaining a reasonably small output voltage ripple.
