摘要：隨著模塊化電源系統(tǒng)的發(fā)展，開關(guān)電源并聯(lián)技術(shù)的重要性日見重要。這里介紹了一種新型并聯(lián)型高頻開關(guān)電源整流模塊的系統(tǒng)設(shè)計(jì)方案。其中，對(duì)開關(guān)電源的驅(qū)動(dòng)電路、緩沖電路、控制電路及主要磁元件進(jìn)行優(yōu)化、設(shè)計(jì)�？刂齐娐芬訳C3525為核心，構(gòu)成電流內(nèi)環(huán)、電壓外環(huán)的雙環(huán)控制模式，實(shí)現(xiàn)系統(tǒng)穩(wěn)壓和限流。并且通過小信號(hào)模型分析，對(duì)電壓電流環(huán)的PI調(diào)節(jié)器進(jìn)行設(shè)計(jì)。 敘詞：開關(guān)電源 PWM 并聯(lián) 均流 模塊 Abstract：With the development of modular power systems, switching power supply parallel the importance of technology has become increasingly important. But here is a new parallel-type high-frequency switching power supply rectifier module of the system design. One of the driving circuit switching power supply, buffer circuit, the main control circuit and magnetic components to optimize the design. Control circuit to UC3525 as the core, a current inner ring, the outer ring of the double loop voltage control mode, and system regulator and current limit. And through small-signal model analysis, the voltage and current Central PI regulator design. Keyword：PWM switching power supply module Parallel Flow
