这项工作提出了设计高输出电压串并联谐振 DC-DC 转换器的综合程序。系统输出电压控制是通过占空比和开关频率变化的组合进行的，其中在整个工作范围内保留软开关。描述了变换器的基本工作原理，并建立了分析模型，为功率部件应力的数值计算提供了基础。此外，还提出了一种最小化空载传导损耗的控制策略，并基于数字仿真讨论了包括输出短路在内的负载阶跃情况下的瞬态行为。
This work presents a comprehensive procedure for designing a high output voltage series-parallel resonant DC-DC converter. The system output voltage control is by a combination of duty-cycle and switching frequency variation, where soft-switching is preserved over the entire operating range. The basic principle of operation of the converter is described and an analytical model is established which does provide a basis for the numerical calculation of the stresses on the power components. Furthermore, a control strategy for minimizing the no-load conduction losses is proposed and the transient behavior in case of load steps including output short-circuit is discussed based on digital simulations.
