從以前到現在電源轉換器是個不可缺少的電子器材，現在消費性產品越來越普遍電源轉換也就越來越多樣化的方式設計，記得早期在設計AC/DC電源轉換器，根據市場調查，5V/12V/20V為主要單組準位設計，每個專案與條件都有規範規定，不同電壓準位就有不同的規格，仔細思考，如果能夠將這些準位變成為可變式輸出電壓，全部相容在一起，變成一機多用途的想法，無論是手機或是平板的產品，或是家電電子產品/網通類電子產品，再加上筆記型電腦(NB)，未來可能桌上型電腦電源的可以適用。
輸出變動式電源設計，符合現在全部的消費性產品，輸出電壓準位範圍非常廣泛，目前最適用的範圍(3.3V~21V)，也就是現在市面上PPS特殊規範，本論文提出一般返馳式降壓型架構與溝通模組，改變變壓器設計與電路平台的調整，來達到最佳化的變動式電源平台。
運用此模組無論是待機功耗，轉換效率，零件應力與保護機制，都可以符合一般電源能效，目前輸出準位可分為(5V/9V/15V/20V)最高效率可以達90%以上，待機功號可以做到小於75mW以下，保護機制也可以維持120%左右的最佳保護點，此方案的重點是電源平台可以達到非常穩定電源機制，最後由整體架構證實電源效率：5V效率可以達到86.8%，20V效率可以達到91.81%。

From past until nowadays, the power adapter is an indispensable electronic equipment. There is a wide diversity of consumer products in the market.
The design of power conversion is becoming more and more diverse. According to the market research, the early-stage design of AC/DC power are designed with 5V/12V/30V as the main one-shot level design. Each product project has its own design specifications, and different specifications for different voltage levels.
If we have different concept that those voltage levels turn into variable output voltage level with the idea of a multi-purpose machine, those devices are all compatible with each other. Whether it is a mobile phone, tablet PC, home appliances, networking device, or notebook computer (NB), it may be possible to use desktop power supply in the future. 
Variable output power supply design, which can meet all current consumer product designs. The output voltage level can cover a wide range, the most suitable range is (3.3V~21V). This is the special specification for PPS（Programmable Power Supply）on the market nowadays. In this paper, we propose a general fly back architecture in buck mode with communication module, so that it could be optimized for variable power platform by changing the transformer design and circuit platform.
With this module, products can meet the general power efficiency in terms of standby power consumption, conversion efficiency, component stress and protection mechanism. At present, output level can be divided into (5V/9V/15V/20V), the maximum efficiency can reach more than 90%, standby power consumption can be less than 75mW. The protection mechanism can also sustain around 120% of the optimum protection point. The key point of this solution is that the power platform can achieve a very stable power supply mechanism, and finally the overall architecture verifies the power efficiency: the maximum efficiency of 5V, which can be up to 86.8% and the maximum efficiency of 20V, which can reached 91.81%.
