Abstract

The class-E power amplifier is widely used due to its high efficiency, resulting from switching at zero voltage and zero slope of the switch voltage (i.e. ZVS and DZVS). This paper presents an analytical expression of the gain between the DC input voltage and the peak switch voltage on an ideal class-E power amplifier (PA) with finite dc-feed inductance, ZVS and DZVS operation. This expression is verified by simulations, and it is evaluated by experimental results at a switching frequency of 10.24MHz. Considering the results (simulated and experimental), the maximum error was 10,2%.
