摘要: 目前多功能电源广泛地应用于各类控制器产品中,传统的驱动控制电源多为单输入单输出形式,难以满足多种供电端口控制设备的需求,且在一些复杂的实验环境和EMI要求较高的产品设备上存在严重的电磁干扰,提高了设计成本。基于反激式开关电源的优势开发了一款低成本、高可靠,兼容AC 220 V或DC 310 V双模式输入,多路输出的高集成度开关电源,现场实验表明4路电源输出精确,误差小于1%,EMI效果好,可满足大部分主板供电设备需求,目前已应用于双冷源除湿机的驱动控制电源。

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.

    目前开关电源在电子工业领域应用较广,在小型化、集成化发展的今天,高精度开关电源已成为工业技术领域发展的必然趋势。反激式开关电源价格便宜,设计简单,体积小,电压调节范围宽,可满足多种电源设计需求[1]。但常规开关电源精度低、纹波大、杂波渗透较率高,输出端口少,难以满足精密设备电源需求,设备因干扰而失控的情况多不胜数。

    针对双冷源除湿机驱动板供电精度要求较高,输入电源要求较多的情况,采用TOP264芯片设计一款AC/DC-DC的双模式输入、多路输出的开关电源,用于给双冷源除湿机产品供电。电源需要满足结构简单、体积小,占空比可跟随输入信号发生变化,使输出电压保持稳定,同时可使系统均衡输出,能根据使用环境要求调整适用范围,为各路负载提供准确可靠的电源。
