摘要
阐述在采用电流模为控制架构的开关电源电路中,需要引入斜坡补偿电路来避免因系统占空比大于50%以后,而带来的次谐波振荡.提出一种全程斜坡补偿办法,通过负反馈结构,实现线性补偿.
Abstract
This paper describes the need to introduce a slope compensation circuit in switch mode power supply circuits using current mode control architecture to avoid subharmonic oscillations caused by system duty cycle exceeding 50%.It proposes a full process slope compensation method that achieves linear compensation through a negative feedback structure.
