英文摘要：

In order to facilitate the analysis of piezoelectric energy harvesting system＇s electrical specification, this paper proposed a method that was to make an equivalent. This equivalent transformed rectifiers and filter circuits to RC circuit. This study analyzed the electrical specification of full-wave rectifier and voltage doubling rectifier, then derived the expressions of resistor and capacitor in the RC equivalent circuit, and simulated the power curves of the resistor before and after equivalent. The results showed that the method that making rectifiers and filter circuits equivalent to RC circuit is feasible.
