Power transformers change voltages and currents to a higher or lower magnitude while also providing isolation of the secondary winding from the power line. By adding taps to the windings, various inputs and outputs can be chosen.
Isolation transformers are used to decouple two circuits. They often have symmetrical windings, and will block the transmission of DC signals from one circuit to the other while allowing AC signals to pass.
Current Ttransfomers are measurement devices that facilitate the safe monitoring of large currents; they are designed to provide a current in the secondary coil proportional to the flowing in the primary.
Step-up or step-down transformers increase (step up) or decrease (step down) AC voltage according to the ratio of primary to secondary turns of wire.
Flyback transformers, typically used in power supplies, are switching transformers that store energy in its inductance during the on time of the circuit. It then delivers the energy to the loda during the off time.
Instrument transformers include current, voltage, and potential transformers which are all used for metering and protection in high voltage circuits.
Current sensing transformers are used to measure current levels for power management and safety protection. They use a single turn primary which is not a part of the transformer itself, but usually a heavy cable or buss bar passed through the transformer core
Autotransformers have a single winding, which is tapped at some point. When AC is appled to the ends of the winding, a lower voltage is produced across a smaller portion of the same winding.
Switch mode power supply transformers are typically used to in inverter circuits to switch two transistors on and off alternately at high frequencies (20KHz to 200KHz).

Transformers

Our engineers specialize in designing custom transformers and inductors to meet specific needs and requirements.

We provide the right configuration with the optimum combination of bobbins, wire types, laminations (or ferrite cores), impregnation and insulation systems.

The ECC engineering staff has over 35 years experience designing all types of transformers and inductors, including:

Whether you need a custom transformer or inductor to meet the needs of limited space, to resist high voltage, to operate in a harsh environment, or achieve other unique requirements, we can help.

We’ve made it easy to determine lamination size and approximate weight based on the VA rating of your transformer. Click here.
