技術說明

一種同步自激式單級高功因轉換器，其中包含一全橋整流器、一電感、一準半橋換流器、一諧振器及一自激訊號變壓器，該全橋整流器與電感連接，該電感與準半橋換流器連接，該準半橋換流器與諧振器連接，該諧振器與自激訊號變壓器連接。本發明具下列優點：1.具高功因 2.具高效率 3.不需積體電路驅動 4.不需外加鐵心做為自激變壓器 5.具零電壓切換 6.具趨近零電流區切換。本電路不同於傳統小鐵心，本電路使用鐵心不需考慮鐵心大小與磁飽和問題，固可驅動大功率的LED路燈照明。 A synchronized self-excited trigger control for single-stage converter with high power factor correction, which includes a full-bridge rectifier, an inductor, a half-bridge inverter, a resonator and self-excited signal transformer, the full bridge rectifier and inductor is connected, the inductive half-bridge inverter with connected, the resonant half-bridge inverter is connected, the resonator is connected with the self-excitation signal transformer. The present invention has the following advantages: (1) high power factor (2) a high efficiency (3) No driver integrated circuit (4) as a self-excited without external transformer core (5) zero voltage switching (6) approaching zero current hand off. Unlike traditional coping small core, the core of the circuit uses without considering the size of the magnetic core saturation problem, the solid can drive high-power LED street lighting.
