摘要
单相桥式整流滤波电路输出电压波形难以用解析式来描述,输出电压波形中,每个周期有一个输出电压下降的时间段.该时间段的长短与滤波电容和负载电阻的数值有关.通过对电路工作过程进行分析,得到相关物理量的数学函数关系式,通过泰勒公式对关系式进行近似简化分析,可以得到电压下降时间段时长与时间参数RC之间的关系式.根据关系式计算得到的数据与电路仿真数据较为接近.关系式可以用于电容值的选取、电压下降时间段时长的计算.
Abstract
It is difficult to describe the output voltage waveform of a single-phase bridge rectifier filter circuit using an analytical formula.In the output voltage waveform,there is a time period during which the output voltage drops in each cycle.The length of this time period is related to the values of the filtering capacitor and the load resistance.By analyz-ing the working process of the circuit,the mathematical function relationship of relevant physical quantities is obtained.By using the Taylor formula to approximate and simplify the relationship,the relationship between the voltage drop time period and the time parameter RC can be obtained.The data calculated based on the relationship formula is rela-tively close to the circuit simulation data.The relationship can be used for selecting capacitance values and calculating the duration of voltage drop time periods.
