摘要
给出了考虑变压器内阻和二极管压降情况下的电容滤波全波整流电路直流输出电压的计算方法,解决了这类电源直流输出电压的定量计算问题。通过计算肯定了滤波电容过大对电源响应速度有负面影响,指出了提高其性能的途径和困难。
Concerning the resistance of the transformer and reduced voltage of diode, the method of calculating the DC output voltage in full-wave rectifier circuit with capacity-input filter is presented. Based on the calculation result, it is confirmed that superfluous filter capacitance has negative impacts on the response rate of the power. Finally, the method to improve its capability is presented.
