Load-Independent Class E Power Inverters: Part I—Theoretical Development

Document Type


Publication Date



An analysis is presented for a class E power inverter that exhibits any of the following characteristics: 1) load-independent, nonzero output voltage, but not load-independent efficiency; 2) load-independent nonzero efficiency, but not load-independent output voltage; or 3) simultaneous load-independent, nonzero output voltage and load-independent nonzero efficiency. Solutions for a class E inverter with load-independent, nonzero output voltage and 100% efficiency are given. The infinite set of solutions is reduced by practical considerations. Circuit parameters for practical load-independent class E inverters are provided. © 1990 IEEE
