# How to convert Direct Current to Alternate Current (DC to AC)? [closed]

I want to make a circuit that converts Direct current to Alternate current. Is it possible at home without using any expensive resources. I know I have to use some resources but I want this as simple as one can.

DC to AC


I know how to convert Alternate to Direct current, but for reverse I don't know how to do this. Someone please help if he can.

I don't know more about electronics. I'm a Software Engineer but I have to work with electronics too.

• This circuit is called an inverter. Before you design one, you need to decide, how what voltage, current, and frequency you want it to operate at. – The Photon Nov 23 '17 at 5:50
• Also, before you make an inverter to supply a device that expects mains voltages, you want to be sure you know enough to do it without electrocuting yourself. – The Photon Nov 23 '17 at 5:53
• If by this you just mean "Can I make an AC sine wave using DC to power it?" then it's not so hard. One or two BJTs can get there. If you want it to actually drive a load such as a speaker with a dozen watts of power, at least another 5 BJTs and a larger DC power supply rail. If you want it to actually provide AC power capable of driving motors, then you want an inverter and it's a much bigger problem. Given the "simple as one can" comment, I'd say you need to focus merely on producing a reasonable sine wave into a modest ($1\:\textrm{k}\Omega$) load. Two BJTs for that. – jonk Nov 23 '17 at 6:49
