Design and analysis of a buck-boost converter circuit for piezoelectric energy harvesting system
The piezoelectric based energy harvesting technique needs to be improved as this system is highly capacitive rather than resistive which limits the current of a resistive load. The efficient way to harvest the energy from the system mostly depends on its interfacing circuitry. It is necessary to...

| Summary: | The piezoelectric based energy harvesting technique
needs to be improved as this system is highly capacitive rather
than resistive which limits the current of a resistive load. The
efficient way to harvest the energy from the system mostly
depends on its interfacing circuitry. It is necessary to
characterize and optimize the interfacing circuit for
maximizing the output power. The circuit parameters - duty
cycle, switching frequency, inductance and load resistance
have been characterized and optimized to improve the
efficiency of the harvesting system. The circuit has been
simulated using PSpice (V16.5) electronic circuit simulation
software. The input voltage of the circuit of the piezoelectric
transducer is 0.54V AC in amplitude and the rated output
voltage has been obtained as 3.3V. The results show that the
maximum output power dissipated in the load is 57mW. |
