摘要: 本文介绍了交错并联技术的基本原理及其优点,详细分析两相交错并联Boost变换器基本原理,分别采用PI控制和数字电流滞环控制方法,简单叙述了两种控制方法的原理并进行优缺点的分析与对比。使用MATLAB仿真,结果显示采用交错并联技术能在很大程度上减小流过开关管的电流,降低开关损耗和输出电压、输出电流纹波;相对于PI控制,采用数字电流滞环的控制方法使得整个电路的性能得到提升。
Abstract: This paper introduces the basic principle and unique advantages of interleaving technology, and analyzes the efficacy of the two-phase interleaved boost converter in detail. In the control part of the circuit, a PI control strategy and digital hysteresis current control strategy are respectively adopted for the sake of comparison. Via MATLAB simulation, interleaving technology is shown to possess a number of important advantages compared to other methods, such as high frequency output voltage ripple with lower switching frequency, reducing current flowing through the switch tube, reducing switching loss, decreasing output voltage ripple, and output current ripple. Compared to the PI control method, the digital hysteresis current control method makes the performance of whole circuit is improved.
