Ac Dc Power Inverter

An AC DC power inverter works by taking the DC (direct current) input and running it into at least one pair of power-switching transistors. The transistors are rapidly turned on and off and that feeds the opposite sides of the transformer. This tricks the transformer into thinking it is getting AC (alternating current).

The DC voltage, which nearly always comes from batteries, is changed into standard AC voltage that is common to most household tools and appliances. Battery voltage inputs are most usually 12, 24, or 48 volts DC. The transformer changes these into 115 volts AC at the output. It is important to note output specifications when looking for an AC DC power inverter.

Some of the things to check include the maximum power and frequency range. Maximum voltage and steady state current are also very important. There are several waveform output choices. The best waveform is the pure sine wave. This is most likely to be produced by the highest quality of inverter. The sine wave converter can run anything.

There is a square wave that is a lesser version of the pure sine wave. The voltage shifts more suddenly from negative to positive and jumps back to negative. This cycle is repeated over and over. Before you trust your appliances or any electrical tool to an AC DC power inverter, read the specs very carefully to make sure you are getting one that will handle the load without ruining the product.
