Many OEMs design new and innovative equipment, systems, and machines that require special considerations throughout their electrical components. In these types of applications, using off-the-shelf types of parts and components is not always feasible.
The various design elements of off-the-shelf single phase transformers may mean a more complicated electrical system within the device. A lower cost option of working directly with a transformer manufacturer to design a customized component reduces the need for increased parts and components and helps to provide optimal performance.
The Requirements
In general, single phase transformers are used with smaller equipment. These transformers are used to transform or change the high AC voltages and currents on main power lines to the correct voltage for use on specific types of electric and electronic devices. Without the transformer, the electronics could not stand up to the voltage and current, and there are different options to consider when choosing the correct option.
While all single phase transformers are passive and operate on an electromagnetic principle known as Faraday’s Law. The current and voltage coming into the transformer passes through the primary windings to generate an oscillating magnetic field in the core, and is stepped down or stepped up to the desired level.
Through induction, this reduced current is passed to the windings on the other side of the field, or the secondary windings, through the electromagnetic circuit.
Factors to Consider
When designing custom single phase transformers, the specific voltage required on the secondary winding and the primary voltage are two essential factors. The number of windings on each side are used to control these specific design requirements. This is also known as the ratio of transformation or turns ratio is a critical consideration.
The type of core material, as well as the size and shape of the transformer, are also elements of the design.
