Ultrasonic Cleaner Powered by Efficient Utilization of Solar Power

摘要

To drive an Ultrasonic cleaner on Solar PV array rated at 18V which utilizes the power coming from the solar panel as efficiently as possible a Boost converter coupled with a Parallel resonant inverter is presented in the paper. A Lithium-Ion battery 36V rated at 3.5Ah is charged by the boost converter and its output is fed to the Parallel Resonant Inverter and the battery parameters like voltage current and the State of Charge(SOC) are to be monitored. The simulation is carried out to achieve a 120 watts output power that is used to drive the transducer placed on the cleaner's floor bed. The output obtained at the end of the Parallel resonant inverter can be used by Ultrasonic cleaning applications. The switching stress and losses get reduced due to the implementation of a parallel resonant inverter. This, in turn, increases the efficiency of the circuit.
