摘　　要：分析了市电直接整流电路滤波电容器的选择方式,讨论了带有和不带有功率因数校正的整流滤波电路的电容器耐压的选择;给出了根据滤波电容器的工作特点提出电容量的选择依据,并对滤波电容器流过的纹波电流是否满足要求。The selecting of filter capacity in rectifier is analieyed, the tolerant voltage of the capacity in with or without PFC are discussed. Accoding to the operation of filter capacity, though the capacity are checked which is satisfied the requirement. select ways are presented, ripple currentthough the capacity are checked which is satisfied the requirement.

关 键 词：电容量 额定电压 纹波电压 纹波电流
