摘要
Abstract
In the application of smart meters, power module often needs to satisfy a wide input voltage range, which can provide a non isolated output voltage taking live line as the ground to supply power for the measurement circuit and MCU control circuit, and another isolated output voltage for the communication circuit. For the above mentioned appli-cation, a new Flybuck converter is proposed. This paper detailedly illustrates the basic circuit structure and operation principle of the converter, emphatically introduces the design method of the high frequency transformer in Flybuck con-verter, and demonstrates that the proposed method is effective and practical through engineering examples. The solution gives a reference for the high efficient and low-cost low power supply.关键词
