本文研究了新的EF 2类逆变器和已知的E类和E/F3类逆变器。本文的目的是找到这个问题的答案：什么应该添加到一个经典的E类逆变器，以提高其性能，以最小的开支？EF 2和E/F3类逆变器通过在零电压开关和零电压斜率开关条件下（如E类）工作并改进晶体管波形（如F类和1/F类）来满足这一要求。E类，EF 2和E/F3逆变器的数值分析的选定结果显示和讨论。分析的目的是最大限度地提高这些逆变器的功率输出能力的软开关条件和固定的电压和电流应力的晶体管作为约束。给出了EF 2和E类逆变器的测量结果，验证了所提出理论的有效性。在1 MHz时，逆变器的输出功率分别为526和366 W，总效率分别为97.1%和96.6
This paper investigates the new Class EF2 inverter and the already known Class E and E/F3 inverters. The purpose of this paper is to find the answer to the question: what should be added to a classic Class E inverter to improve its performance with minimum expenditure? Class EF2 and E/F3 inverters meet this requirement through operating under zero-voltage switching and zero-voltage slope switching conditions (as in Class E) with improved transistor waveforms (as in Class F and 1/F). Selected results of a numerical analysis of Class E, EF2 and E/F3 inverters are shown and discussed. The analysis is aimed at maximizing the power output capabilities of these inverters for soft-switching conditions and fixed voltage and current stresses on their transistors as constraints. Measurement results of the Class EF2 and E inverters are given to verify the validity of the presented theory. The measured output power of the inverters was 526 and 366 W with the total efficiency of 97.1% and 96.6% at 1 MHz, respectively
