摘　　要：研制了采用集成芯片UC185 4的BOOST高功率因数变换器 .它是基于电流跟踪技术、通过控制电感电流使其按正弦半波规律变化来提高网侧功率因数的 .实验表明 ,该系统电路简单 ,输入电流失真度低 (实测波形失真率 <5 % ) ,功率因数高 (cosφ =0 .99) ,可明显改善电网运行质量 .A new BOOST high power factor convertor using integrated chip UC1854 is developped.It is based on the technique of current tracking,and enhances electrical network's power factor through controlling inductance's current to make it change according to half wave of sin function.The experimentation indicates that this system has the advantage of current's simpleness,low input current's distortion rate (value of testing<5%) and high power factor (cos φ =0 99) which can improve the quality of electrical network obviously.
