| Summary: | A piezoelectric micro-energy harvesting system is
composed of piezoelectric transducer, rectifier, DC to DC
converter and storage device. Parameters of the DC to DC
converter have been optimized to harvest maximum energy from
piezoelectric transducer. The key parameters are switching
frequency, duty cycle, output load and inductance have been
studied. The input voltage of the circuit from the piezoelectric
transducer of 0.3V AC amplitude and output DC load voltage of
1.91V are considered. The circuit has been simulated using
PSpice (V16.5) electronic circuit simulation software. The results
show that the efficiency of the energy harvesting circuit is 34%
and the maximum output power across the load is 3.69mW. |
