A Sustainable Alternative To The Batteries Used In IOT Devices

Abstract

A lot of studies have shown that the synchronous switch energy producer solutions increase the rate of energy production from vibration (i.e.) piezoelectric ones which comes with capacitive output impedance. These ones use inductive branch to compensate capacitive source. Some studies have done the reciprocal (i.e.) to compensate inductive source they use capacitive branch. In these, the controllers are very bulky which is not a desired ones for making sustainable energy for the IOT devices. This synchronous switch method will work with two rounds of ON/OFF actions in each vibration cycle. By this method we can improve the power factor, thus the energy production is increased. This method uses very less amount of switching actions than other methods we use just like pulse width modulation ac-dc rectifier designs. The detailed working is given in this article. It also shows the result proving that this synchronous switch method outperforms the diode- bridge rectifier energy converting methods by 62.1%-96.4%.
