DC/AC Inverters: How Do They Work?

D.C. to A.C., DC/AC, Direct Current to Alternate Current, DC to AC Inverter.

Today, we are going to talk about the current and current’s converters, more specifically, the Inverter circuit, who allows converting the Static Direct Current, known as D.C. to Alternate Current – A.C.

With the inverter module’s help, you can power different home AC Net-“dependent” appliances, directly, e.g. using your vehicle battery.

You Can power a small Refrigerator or a cooler.

You can power & charge:

The random kind of Laptop,
Drone UAS, powering You Game-Station,
PlayStation PS2, PS3, PS4, PS4 pro, the Newest 2018 not released yet PS5,
XBox, Xbox One X,
Nintendo, Nintendo Switch,
Even use the standard Soldering Iron, till you practice your nice hobby in the open.

The last “extra” will be understood only by You, Dear “High-Level” of Electronics freaks.

The Lecturer is a talking about the principle of DC – to AC Sinusoidal Waveform inverter.

During the How does it work Demo example, he successively uses the simple mechanical switches, then part by part slowly complicated the schematics in a way to maximize a “success rate” during the learning process.
