Abstract
Because of their high operating efficiency, class E circuits have been shown to be useful in high-frequency power inverters and converters. Typical circuits are constant-current-fed, i.e., they require an RF choke in the dc-feed line, and must obtain load regulation by means of appropriate feedback control. A class E inverter with finite dc-feed inductance that provides perfect load regulation without feedback control has been suggested 113]-|15]. However, such class E circuits generally have higher sensitivities to component variations (except load resistance) than do their constant-current-fed counterparts. Thus, the possibility of load-independent operation of constant-current-fed class E inverters is of interest. This paper shows that there is no way to configure a constant-current-fed class E inverter so that it will exhibit load-independent properties except for a trivial circuit with zero output voltage. © 1990 IEEE
