What is an Inverter?
An inverter is a device that converts the power received from external batteries into electricity that can power your home and appliances. It works by converting DC voltage into AC voltage, meaning it converts a direct current into an alternate current to match the voltage requirements of South African home applications.
How Does an Inverter Work?
A basic circuit includes an oscillator, control circuitry, a driver circuit for the power device, switches, and a transformer. To convert DC power into alternating voltage, we must convert the DC power in sources, such as a battery, into alternate energy.
This is achieved using switching devices which are continuously turned on and off, and then stepping it up using the transformer. There are some configurations that don’t use transformers, but they’re not commonly used.
As mentioned earlier, the power device that feeds the pulse signal to the primary coil of the transformer switches ON/OFF the DC input voltage. Fluctuating voltage in the primary coil causes an alternating voltage in the secondary winding. The transformer also amplifies the output voltage at a rate determined by the turn’s ratio.
In most cases, this means raising it from 12V to 230V AC. The top three inverters commonly used include a push-pull full bridge, half-bridge, and a push-pull with centre tap transformer. The latter is most popular because it is simple and gives guaranteed results, although it is less efficient and uses a heavier transformer.
