摘要: 目前多功能電源廣泛地應用于各類控制器產品中,傳統的驅動控制電源多為單輸入單輸出形式,難以滿足多種供電端口控制設備的需求,且在一些復雜的實驗環境和EMI要求較高的產品設備上存在嚴重的電磁干擾,提高了設計成本。基于反激式開關電源的優勢開發了一款低成本、高可靠,兼容AC 220 V或DC 310 V雙模式輸入,多路輸出的高集成度開關電源,現場實驗表明4路電源輸出精確,誤差小于1%,EMI效果好,可滿足大部分主板供電設備需求,目前已應用于雙冷源除濕機的驅動控制電源。

Abstract: At present, multi-functional power supply is widely used in all kinds of drive control products. The traditional drive control power is mostly single input and single output, which is difficult to meet the needs of a variety of power supply port control equipment. Moreover, there is serious electromagnetic interference in some complex experimental environment and products with require high EMI requirements, which improves the design cost potential. To solve the above problems, a low-cost, high reliability, compatible with AC 220 V or DC 310 V dual-mode input, multi-channel output and high integration switching power is developed. Field experiments show that the four power output is accurate. The error is less than 1% and electromagnetic interference is easy to pass. The power can meet the needs of most motherboard power supply equipment, and has been applied to driving control power supply for double cold source dehumidifier.

目前開關電源在電子工業領域應用較廣,在小型化、集成化發展的今天,高精度開關電源已成為工業技術領域發展的必然趨勢。反激式開關電源價格便宜,設計簡單,體積小,電壓調節范圍寬,可滿足多種電源設計需求[1]。但常規開關電源精度低、紋波大、雜波滲透較率高,輸出端口少,難以滿足精密設備電源需求,設備因干擾而失控的情況多不勝數。
針對雙冷源除濕機驅動板供電精度要求較高,輸入電源要求較多的情況,采用TOP264芯片設計一款AC/DC-DC的雙模式輸入、多路輸出的開關電源,用于給雙冷源除濕機產品供電。電源需要滿足結構簡單、體積小,占空比可跟隨輸入信號發生變化,使輸出電壓保持穩定,同時可使系統均衡輸出,能根據使用環境要求調整適用范圍,為各路負載提供準確可靠的電源。
