摘要
电力电子装置的大量使用，给电网带来了严重的谐波污染。以Motorola公司最新推出的功率因数控制芯片MC33368为核心，设计了一种宽电压输入范围、固定升压输出的175W的AC/ DC变换器，详细给出了系统的参数设计。
The extensive application of the power electronic converters unavoidably produces more and more harmonics.A 175W AC DC converter,which has universal input and fixed output voltage is designed based on MC33368.The system parameters design is given.The experiment results show that the APFC can achieve fixed boost output 400V voltage in the universal input range of 92～270v,meantime,power factor is 0 99 and the total THD is no more than 6%.
