This paper presents the results of experimental analysis of piezoelectric-based power conversion circuits under vibration. Three types of circuits were evaluated: a standard full bridge rectifier (S-FBR) circuit, a self power synchronous electrical charge extraction circuit (SECE-sp), and an optimized self power synchronous charge extraction circuit (SECEopt-sp). Experiments were conducted to evaluate the effectiveness of energy conversion under real operating conditions. The results showed that the SECEopt-sp scheme has the highest energy conversion effectiveness and stable output power, outperforming other tested schemes. The optimum operating parameters of the circuit are identified to ensure minimum energy loss and maximum output power. SECEopt-sp provides maximum output power and stability under varying load conditions. Thus, SECEopt-sp was found to be the most efficient circuit for harvesting energy from low-frequency mechanical vibrations such as water motion or waves.
