摘要

介绍了一种电容式空转开关电源变换器的新型控制方法。通过一种新颖的开环控制策略在一次侧提供输入电压调节，而通过经典反馈控制在二次侧实现负载电流调节。从空载到满载的优秀线路和负载调节特性在250 W三输出的CI Cuk转换器原型上得到验证，该转换器提供了对所有输出的完全调节和独立保护，以及初级和次级侧控制电路的简单同步。仅在主电源变压器中需要隔离

Capacitive idling Cuk converter with a novel control scheme

A novel control method is introduced for a capacitive idling (CI) class of switching power converters. Input voltage regulation is provided on the primary side via a novel, open-loop control strategy, while load current regulation is implemented on the secondary side via classical feedback control. Excellent line and load regulation characteristics from no load to full load are verified on a 250 W triple output prototype of a CI Cuk converter providing full regulation and independent protection of all outputs and simple synchronization of the primary and secondary side control circuits. Isolation is needed only in the main power transformer.<>
