Abstract_Chinese:\r本文主要介绍了微型自供电系统中的一种类型——驻极体发电机的工作原理，针对微型发电机的特点，引入了边缘效应，验证了驻极体发电装置的理论输出功率模型，分析验证了微型电容在考虑边缘效应情况下的实际输出功率，根据实际输出功率模拟得出理论模型，从而得出在考虑边缘效应的情况下，微型自供电驻极体发电装置的
输出功率模型．并且将BJ 模型与FE-BJ 模型进行对比，通过MATLAB 仿真软件得出忽略边缘效应时，平板电容的宽度与间距比小于28.724 时，FE-BJ 模型的输出功率误差在10%,以内，此时可用FE-BJ 模型来模拟计算微型驻极体发电装置的输出功率．\r

Abstract_English:\rThis paper mainly introduces the working principle of one type of electret generator in micro self-powered system. According to the characteristics of the micro generator，the fringe effect was introduced to verify the theoretical output power model of the electret generating device and analyze the micro capacitor in consideration of the actual output power under the condition of fringe effect. The theoretical model was simulated according to the actual output power and thus the output power model of self-powered micro electret generating device was concluded，considering the fringe effect. Boland Justin(BJ)model and fringe effects-Boland Justin(FE-BJ)model were compared and it was calculated by use of MATLAB simulation software that ignoring the fringe effect，width and spacing ratio of plate
capacitor is less than 28.724 and the output power error of FE-BJ model is less than 10%. Under these circumstances FE-BJ model can simulate the output power of micro electret generating device.\r
