We present a new technique of equivalent circuit modeling technique for micro electret vibration power generators. It characterizes the electro-mechanical behavior of the power generators, and expresses as an equivalent circuit model. We explain the technique and implement the equivalent circuit model to a circuit simulator, called LTSPICE. Our experimental results demonstrate that our equivalent circuit model is very accurate. They also reveal that our technique has the capability of dealing with the practical industrial circuit design and circuit analysis.
