Transformers transfer electrical energy from one electric circuit to another, typically by the principles of electromagnetic induction. Transformer types include potential, current, step-up, step-down, distribution and others.
Audio transformers improve sound quality by removing interference from audio signals.
Autotransformers are a special type of power transformer with only one winding.
Board mount transformers are transformers designed to be embedded in or mounted on computer boards.
Cast coil transformers have windings that are solidly-cast in resin under a vacuum in a mold. This manufacturing process covers the transformer windings in a strong epoxy resin with a high dielectric strength.
Constant voltage transformers (CVTs) or ferroresonant transformers produce a constant secondary (output) voltage for varying primary (input) voltages within a certain range.
Current sense transformers are used to detect and measure current. There are two basic types of products: switch-mode transformers for power conversion applications, and precision-measurement transformers for instrumentation applications.
Current transformers are used to step down current in a very predictable fashion with respect to current and phase. They are generally used as inputs to current instruments.
Distribution transformers are pole-type transformers that supply relatively small amounts of power to residences. They are used at the end of an electrical utility’s delivery system.
Electronic transformers are designed especially for low-power applications. They are used in computers, radio frequency (RF) devices, and lighting.
Flyback transformers (FBT) or line output transformers (LOPT) are designed to produce a very high voltage by storing energy in their magnetic windings.
Gate drive transformers are used to modify the voltage level to a gate. They also provide impedance matching and voltage isolation.
Harmonic mitigating transformers use phase-shifting, electromagnetic flux cancellation, and source impedance to reduce harmonic currents in electrical distribution systems.
Industrial control transformers are designed for industrial applications that require relays, solenoids, and other electromagnetic devices. They contain capacitors or other filtering devices to minimize variations in output, and are well-suited for applications that require constant current or constant voltage with a low volt-amp or low power rating.
nstrument transformers are used to step-down current or voltage to measurable values. They provide standardized, useable levels of current or voltage in a variety of power monitoring and measurement applications.
Isolation transformers provide electrical decoupling or isolation to two connected circuits. They have a turn ratio of 1:1.
Power transformers convert power-level voltages from one level or phase configuration to another. They can include features for electrical isolation, power distribution, and control and instrumentation applications.
Pulse transformers interface a pulse forming network (PFN) and a load. They match the impedance of the load to the PFN in order to maximize power-transfer efficiency.
RF transformers transfer energy from one circuit to another by electromagnetic induction. Typically, they are used to increase or decrease voltage as it passes from one side through the other.
Signal transformers transfer information from one circuit to another by electromagnetic induction. They are used to increase or decrease the voltage from one side of a power transformer to the other.
Single-phase transformers output single-phase AC power, typically while stepping-up or stepping-down the voltage between two circuits.
Switch mode transformers (switching transformers) are used mainly in switching power supplies and DC-DC converters. They provide a storage element for transferring energy from input to output in discrete packets as required in switching power supplies, regulators and converters.
Telecom transformers are used in applications which require high bandwidths and fast switching speeds. They isolate the signal between primary and secondary grounds. This product area includes DSL, xDSL, T1, E1, ISDN, LAN, WAN, Ethernet, ATM and modem transformers.
Three phase transformers are designed to supply electric power to three-phase systems.
Toroidal transformers typically consist of copper wire wrapped around a cylindrical core. This design prevents the magnetic flux that occurs within the coil from leaking.
Transformer winding services design transformers and other magnetics products for application-specific and OEM usage in a variety of industrial, medical, military, aerospace, telecommunications, commercial and specialty applications.
Transformers are electrical devices that are designed to transfer energy from one circuit to another by electromagnetic induction. They are used typically to increase or decrease voltage as it passes from one side of the device through the other.
Voltage and potential transformers are used to measure voltage (potential). The secondary voltage is substantially proportional to the primary voltage and differs from it in phase by an angle that is approximately zero.
