On the feasibility of load-independent output current in class E amplifiers

The conventional class E topology can be configured to achieve simultaneous load-independent output voltage and load-independent efficiency. Because its dual may also provide load-independent voltage, the conventional topology was examined for the possibility of simultaneous load-independent output current and load-independent efficiency. It is shown that the only solutions to the sets of equations describing simultaneous load-independent output current and load-independent efficiency are impractical.<
