摘要
以开关电容耦合电感变换器为研究对象,详细设计了其主电路参数及器件选型,涵盖DC-DC高升压电路的运行工况、耦合电感、电容以及开关管和二极管的合理配置;同时设计辅助电路与控制单元,采用光耦隔离驱动方式和霍尔电压传感器,实现信号的稳定传输与精确检测,并结合DSP控制系统完成闭环稳定调控。为验证设计的有效性,搭建200 W实验样机,实验结果证明该变换器具有高电压增益、稳定输出特性、较高转换效率及在闭环控制下快速响应输入变化的能力。该设计为电力电子实验教学提供了一个创新且实用的实验案例。
Taking the SCCL converter as the research object,we design its main circuit parameters and device selection in detail,including the operating conditions of the DC-DC high boost circuit,the coupling inductance,capacitance as well as the reasonable configuration of switches and diodes.In addition,auxiliary circuits and control units are also designed.Using optocoupler isolated drive method and Hall voltage sensor,stable signal transmission and accurate detection are realized,and combined with DSP control system closed-loop stable regulation is also realized.In order to verify the validity of the design,a 200 W SCCL experimental prototype is built and its high voltage gain and stable output characteristics are experimentally verified.The experimental results show that the converter not only has high conversion efficiency and stability,but also can respond quickly to the input changes under closed-loop control,which verifies the correctness of the design.This study provides an innovative and practical experimental case for power electronics experimental teaching,and improves the quality of teaching and the practical ability of students.
