The Class E power amplifier is a new type of tuned power amplifier, which was invented and described by Sokals and its theoretical analysis was presented by Rabb. In recent years, the engineering application of the class E power amplifier is the main topic of discussion. 高效率E类功率放大器是一种新型的开关模式功率放大器,由Sokals发明,Raab作了理论上的分析,但至今还不完善,近年来,工程应用研究是讨论的主要课题。
