摘要

It's a good way to improve the efficiency of a resolver power drive circuit by the principle of class-F amplifier. In (his paper, in order to meet the basic working conditions of class-F amplifier, composed a load-network of a resolver equivalent circuit and external elements to meet the resonance frequency of harmonics. The feasibility of a high efficiency class-F resolver power drive circuit was observed by Simulink simulation.%利用F类放大器的原理设计旋转变压器功率驱动电路是提高工作效率的有效途径.本文根据F类放大器的结构形式,将旋转变压器等效电路与外部元件配合构成满足不同谐波要求的负载网络,实现了F类放大器的基本工作条件.通过Simulink仿真实验的波形分析证实了利用F类放大器原理提高旋转变压器功率驱动电路工作效率的可行性.
