Improvement of Output Power from Vibration Generator Using Internal Capacitor Cancel Control Rectifier for Vibration up to Third Harmonics

Abstract

Recently, vibration generators have attracted considerable attention. Generally, vibrations include not only the fundamental frequency but also any harmonics. We proposed an internal capacitor cancel control (ICCC) rectifier to improve the output power. The proposed rectifier nullifies the internal capacitor to improve and maximize the output power. Using numerical methods, our previous paper theoretically revealed that the proposed rectifier for the vibration generator improved the output power. This study experimentally analyzes the improvement of the output power from vibration generator by using the proposed rectifier for vibrations, including the third harmonics.
