Abstract

The feasibility of applying standard commercial ceramic capacitors (CC) for controlling a series resonant converter was examined by a simulation model that was calibrated experimentally. The study reveals that the CC could be a viable control element for resonant converters. It is shown that CC controlled series resonant converter can be operated under ZVS. The results of this study show that control attributes of the capacitor controlled SRC are identical to those of the conventional frequency controlled SRC, if the range of the capacitor change is equal to the range of the frequency change in the conventional converter, squared. Based on the present investigation, capacitance ratios of 1:5 can be practically achieved with commercial CC. It was found that the nonlinearity nature of the CC has only a minor effect due to the narrow bandwidth nature of resonant converters.
