Technical FAQs 4

How a 12V inverter works?

The inverter has a simple working principle as Figure 1. Which first important thing is the transformer. The most common type of transformer is the laminated core, 12V-CT-12V. Normally, the 220V winding is primary. Then, 12V is secondary, the output is 12V. But this turns. the 12V winding is input or primary.

How to choose a battery inverter?

The battery should have the power more than 1A. The inverter has a simple working principle as Figure 1. Which first important thing is the transformer. The most common type of transformer is the laminated core, 12V-CT-12V. Normally, the 220V winding is primary. Then, 12V is secondary, the output is 12V.

How many volts does a transformer use?

If your powerline frequency is 50 Hz, you need 60/50 times the above result for your primary for 120 V, and twice that for 240 V. A transformer has a maximum volts per turn. You need to have sufficient number of turns on the primary so that the primary voltage you apply, divided by the number of turns, does not exceed this volts per turn.

How much inductance does a 240V 50/60hz transformer have?

The inductance is proportional to the number of turns squared, and a small 120/240V 50/60Hz mains transformer primary might be some hundreds of turns, so you can see how far off a single turn is. At a fraction of a volt, or higher frequencies at relatively low voltage, a single-turn primary might make some sense.
