利用傅里叶级数方法对串并联谐振变换器（SPRC）工作在连续导通模式（CCM）下的稳态特性进行了频域分析。性能参数的方程推导出稳态条件下，提供简单的设计工具。SPRC的拓扑结构结合了串联谐振变换器（SRC）和并联谐振变换器（PRC）的优点。工作的主要结果是：一种新型的半波整流SPRC，获得高的部分负载效率的条件;和几个边界频率和限制条件，如电容/电感负载边界和开路和短路的情况。在不同的负载电阻和输入电压的谐振以上的80 W的转换器测量的实验结果显示出良好的协议与理论性能的方程预测。>
A frequency-domain steady-state analysis is given for a series-parallel resonant converter (SPRC) operating in the continuous conduction mode (CCM) using Fourier series techniques. Equations for performance parameters are derived under steady-state conditions to provide simple design tools. The topology of the SPRC combines the advantageous properties of both the series resonant converter (SRC) and the parallel resonant converter (PRC). The key results of the work are: a novel half-wave rectifier SPRC, conditions for obtaining high part-load efficiency; and several boundary frequencies and limiting conditions such as the capacitive/inductive load boundary and open-circuit and short-circuit cases. Experimental results measured for an 80-W converter above the resonance at different load resistances and input voltages show excellent agreement with the theoretical performance predicted by the equations. >
