Abstract

Class-E dc/dc converters can operate at high switching frequencies with very low switching power losses. Using commercially available power transistors and diodes, Class-E converters can operate at switching frequencies in the low-MHz range, with efficiencies of about 85%. Previous papers dealt with the circuit parameter values needed to obtain high-efficiency operation and output-voltage regulation, and with the static control characteristic of the Class-E dc/dc converter cell. Here we extend the analysis to include the dynamic control characteristics and further information about the static characteristics. The theoretical predictions are verified by experimental measurements on a 40-watt 1.5-MHz converter.
