What is an Inverter Duty Transformer?

 

Inverter duty transformers (IDT) can be understood as one type of power transformer only. They send electrical energy from the source to the destination without altering frequency, making them useful in applications which require maintaining the same frequency.

Technically, the inverter duty transformers are designed to step up or step down the voltage levels depending on the specific application requirement. It is mainly used in power distribution systems to step up or step down power voltage and transmitted over long distances.

So, how do these transformers work?

How Do Inverter Duty Transformers Work?

Inverters convert direct current (DC) to alternating current (AC) at a lower voltage from sources such as solar panels; the inverter transformer steps up this voltage level to a higher value that is compatible with the electrical appliances to run.

Once the inverter generates the AC output, it is directed into the primary winding of the inverter-duty transformer. Then, the AC flowing through the primary winding creates a fluctuating magnetic field within the transformer core, inducing a voltage in the secondary winding.

Now, the secondary winding is specifically designed with a different number of turns to achieve the required voltage step-up or step-down ratio based on what the system requires.

Basically, IDTs help inverters convert the DC power into alternating power within batteries and solar panels. They do so by switching the polarity from positive to negative for the output, creating a square wave. While the square wave has an increased voltage with a reduced current, the power output remains the same as the input power.

Applications of Inverter Duty Transformer

Here are some applications of IDTs:

• In windmill power transmission systems, inverter transformers convert stored DC energy into AC. Mostly, this AC power is used in remote areas either for residential or industrial purposes. Otherwise, it is sent to the electricity grid.

• Photovoltaic grids, which are powered by solar energy, include multiple solar panels, a few inverters, a power conditioning unit, and equipment for connecting to the grid. In these systems, IDTs help convert DC power into AC before the power is transmitted to the grid or power stations.

• Inverter transformers also find applications in elevator operating and backup systems to maintain smooth operations and ensure safe rides.

• Machinery control panels, which contain various electronic devices that send signals to ensure machines and equipment operate correctly, rely on inverter transformers for smooth functioning.

• For applications with non-linear loads, where harmonic currents are common, inverter transformers help generate pure sine waves that can be transmitted over long distances.
