              Inverters are also required at locations where AC supply from the Mains can not be accessed. In order to convert DC power to AC power, an inverter circuit is used. Two kinds of True/pure sine wave inverters and quasi-or modified inverters may be inverters. Although modified or quasi-inverters are inexpensive, these true/pure sine wave inverters are costly.

A square wave is generated by these adjusted inverters and is not used to power sensitive electronic equipment. Here a simple inverter circuit powered by voltage is designed using power transistors as switching devices that convert 12V DC signal to 220V AC single phase.



An AC current is converted to a DC current by a power converter. The converter will kick in and take the 120V coming in and reduce it to 12V for the stuff that need it when you’re plugged into shore electricity, like sending a current to your house batteries to recharge them. Usually, these come normal on RVs.

The same is achieved by a power inverter. The inverter takes the 12V current and converts it to 120V current when you run off your batteries or solar panels, such as when you’re out boondocking, to give it to the things that need it. Most of the products in an RV will draw DC, but some of the more residential things will need AC, such as residential refrigerators, TVs, space heaters (some prefer to use them to minimise the use of propane), microwaves, etc.
