Abstract
In our project we worked on operating refrigerator by converting the sunlight that hits the solar cells to electrical power. Solar array convert the sunlight to DC power then the battery stores this DC power, then we designed an inverter to invert the DC power into AC power.
We designed this inverter to invert DC power with 12VDC into AC power with 12VAC, and our inverter consists: Aduino Nano to operate PWM signals, Voltage regulator circuit gives (5V) to operate the Arduino, Drive gates (IR2110) controlled by the Arduino and this drive gates used to drive the next part of our inverter which is H-Bridge which consists of 4 MOSFETs (IRF840) and the last part of the inverter which is LC filters to give a pure sine wave.
Then this AC voltage will enter the transformer to step-up the voltage that the refrigerator needs.
