对于开关电源的调节和保护电路,容差是需要考虑的一个关键因素。统计学表明实际产品特性参数都是服从正态分布的,需要使用蒙特卡罗方法来做容差分析。在文中介绍3种容差分析的方法,并对这3种方法进行相互验证与比对。
For the switching power supply regulation and protection circuit, tolerance is a key factor to be considered. Statistics show that the actual product characteristic parameters are subject to normal distribution, need to use the Monte Carlo method to do tolerance analysis. In this paper, three kinds of tolerance analysis methods are introduced, and the three methods are verified and compared with each other.
