并聯型高頻開關直流電源的系統設計

摘要：隨著模塊化電源系統的發展，開關電源并聯技術的重要性日見重要。這里介紹了一種新型并聯型高頻開關電源整流模塊的系統設計方案。其中，對開關電源的驅動電路、緩沖電路、控制電路及主要磁元件進行優化、設計�？刂齐娐芬訳C3525為核心，構成電流內環、電壓外環的雙環控制模式，實現系統穩壓和限流。并且通過小信號模型分析，對電壓電流環的PI調節器進行設計。 敘詞：開關電源 PWM 并聯 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
