Abstract

In this paper analysis and digital controller design for digital voltage-mode controlled higher order boost converter (HOBC) is presented. The state-space averaging method is applied to formulate the small-signal models; valid up-to half of the switching frequency, of the converter and a loop gain is adapted to design the voltage-mode discrete compensator. Closed-loop performance of the HOBC is analyzed. The results of controller design and closed-loop analysis are illustrated through computer simulations for 48 V applications. In this paper analysis and digital controller design for digital voltage-mode controlled HOBC is presented. The state-space averaging method is applied to formulate the small-signal models, valid up-to half of the switching frequency, of the converter and a loop gain is adapted to design the voltage-mode discrete compensator. Closed-loop performance of the HOBC is analyzed. The results of controller design and closed-loop analysis are illustrated through computer simulations for 48 V applications.
高阶升压变换器的数字电压模式控制
本文对数字电压模式控制的高阶升压变换器(HOBC)进行了分析和数字控制器设计。采用状态空间平均法建立小信号模型;有效的开关频率可达变换器开关频率的一半,环路增益可用于设计电压型离散补偿器。分析了HOBC的闭环性能。通过对48v应用的计算机仿真,说明了控制器设计和闭环分析的结果。本文介绍了数字电压模式控制HOBC的分析和数字控制器的设计。采用状态空间平均法建立了变换器的小信号模型,有效频率为开关频率的一半,并采用环路增益设计了电压型离散补偿器。分析了HOBC的闭环性能。通过对48v应用的计算机仿真,说明了控制器设计和闭环分析的结果。
