Optimizing the Output Voltage of Piezoelectric Energy Harvesting with DC-DC Booster Circuit

A vibration-based low-voltage DC-DC boost converter is presented in this research. Powering a gadget with less than 1V energy needs a boost circuit, a switching gate boost converter was utilized to enhance the input voltage for low vibration frequency. To determine the optimal duty cycle, inductance, and load capacitance for a booster circuit, L Tspice XVII software was used with input less than 1 V. The output voltage range from 26V to 61 V increases linearly with the input voltage range from O.3V to O.7V. the best parameters for a 10k load are a 50uH inductor and a 10uF load capacitor. The voltage converter is suitable for vibration energy harvesting in automotive, healthcare, and wireless sensor network applications with low input voltage and low frequency in the KHz range
