The objective of this proposal is to develop a modified class E         switching-mode radio frequency power amplifier to be utilized as the            power invertor cell of distributed power conversion systems.  Equations         describing class E invertor operating parameters will be developed and          solved using a computer symbolic manipulation program to achieve class E        invertor circuit configurations that provide extremely high efficiency          and output voltage independent of load without inherently requiring             feedback control.  The determined circuit configurations will be used to        construct and evaluate prototype class E power invertor cells.                  Measurements of input power, output power and voltage, efficiency and           output harmonic content will be made to determine the feasibility of            utilizing this radio frequency circuit design technique in practical            power conversion systems with reactive and/or utility interaction loads.        Such invertor cells may be used to realize distributed power conversion         systems that are smaller, lighter, and operate with increased overall           efficiency and greater reliability at reduced cost.
