How to convert DC current into AC ?Explain with a diagram.

Name of the device which converts dc to ac is inverter.

Working:-

The inverter working principle as shown in Figure 1. The main device is a transformer. Which have 12V-0-12V, a common iron core. But instead we use the power input as 220 volts. Then power output as 12 volts. The way the switch differential is power AC input as 12 volts and output to AC 220 volts.The 12 volts input power source is a battery Be Supply into the center tap of the coil 12 volts. Which is now considered a power pack or coil primary. The ends of the wire on both sides (points A and B) And it will be connected via a 2-way switch to ground.Which if the switch connected at A point, will cause an electric current number one, flows from the positive terminal of the battery, into the center tab point. Then flows up to the top, through the contacts A of the switch to ground.If the switch is moved from Points of A to the Points of B, would make an electric current No. 1 has stopped. Because currents will redirect the flow an electric current is number 2. From the center tap down below. Through contact B of the switch to ground.The 2 way switch will be controlled on-off with the oscillator circuit that as the frequency generator of 50Hz As a result, switch off – on back and forth between Points of A and B with a speed of 50 times per second. Makes an electric current No. 1 and No. 2 alternating flow rate of 50 times per second as well. Which current flowing through the switch all the time like this.Makes magnetic field resulting in swelling and shrinkage. And induced across to the 220 volts coil. Which is now considered to be a output power or secondary coil. The resulting voltage 220V AC 50Hz frequency winding up this series. The voltage available to be supplied to the various types of electrical voltage to 220 volts AC to operate.
