When you want to use the pure sine wave inverter to power the electronic appliances in your home, you must know the working of the device. The inverter is not just used during power failures, outages, but it can be used outdoors. The power inverter has power outlets through which you can connect the appliances.
However, the appliance that you can connect depends on the ratings and load capacity the inverter can handle. After connecting and turning on the inverter, it converts the DC current into AC current with which the appliances work. It also powers sensitive appliances and makes them work optimally.
The circuit or device connected to the inverter will have an impact on the frequency, output voltage, power handling, and various other factors. It delivers a clean and consistent power that is required for the appliances to function without any interruption and surges, especially when you are connecting the devices off the grid.
The operation of the inverter is based on three different stages. These include:
Oscillation stage
The inverter will generate pulses when it is passed through the IC circuit. The voltage that is generated will have a particular frequency. Both the negative and positive voltages will oscillate at a specific frequency. These weak signals are tough to supply power to the high current output transformers. You can improve the strength of the weak signals by setting up an amplifier. It improves the signals and allows the inverter to perform the task.
Booster or amplifier stage
The voltage that is generated by the oscillator would be amplified using the amplifier and take the low current levels to the operating levels. The power that is amplified would be in the AC form. However, the voltage is supplied by the battery and is too low for the appliance to run. You can raise the voltage levels to make the appliance function optimally by amplifying the voltage levels. This increased voltage is passed to the secondary winding of the output transformer.
Output transformer stage
The transformer will reduce the AC levels with the help of magnetic induction. The transformer acts as a power inverter, but the other way around. The lower AC power that is in the amplifier stage is passed to the secondary winding of the transformer that is in the output stage. The voltage is increased, and the inverters use this voltage to power up the AC appliances connected to it.
