Abstract
The performance of a single transistor class E amplifier operating at 13.56 MHz has been studied. Based on the operating data, parallel operation of devices has been achieved. Both circuits use the output capacitance of the transistor as one of the circuit elements. The method of selecting a suitable switch is described. An output power of 160 W at an efficiency of 78.3% has been obtained from the single device and two devices operating in parallel produced 286 W at an efficiency of 70.0%.
