Switch Mode Power Transformers – Custom Built
A switched-mode power supply (also switching-mode power supply, SMPS, or simply switcher) is an electronic power supply unit that incorporates a switching regulator in order to provide the required output voltage. The switch mode transformer is used in conjunction with the switching regulator to form a swicth mode power supply.
Switch mode power transformers are used extensively in electronic applications, usually within a switch mode power supply:
- Computer power supplies
- Cell phone charging units
- Lighting applications
- Laser power supply
The specifications of a switching transformer usually includes:
- Circuit Topology: Flyback, Feed Forward or Blocking Oscillator
- Power Rating in VA
- Input Voltage in volts
- Peak Input Current in Amps
- Operating Frequency in kHz
- Secondary Voltage in volts
- Secondary Current in Amps
***These specifications are specific to applications.

Butler Winding designs switching mode power transformers and inductors for buck, flyback, boost, and inverter applications in a wide variety of shapes and sizes. This includes various standard types of “core with bobbin” structures (E, EP, EFD, PQ, POT, U and others), toroids, and some custom designs. Our upper limits are 40 pounds of weight and 2 kilowatts of power.
We have experience with foil windings, litz wire windings, and perfect layering. For toroid transformers, we can sector winding, progressive winding, bank winding, and progressive bank winding. Butler winding has a variety of winding machines, bobbin/tube and toroid. That includes two programmable automated machines and a taping machine for toroids. Butler Winding has vacuum chamber(s) for vacuum impregnation and can also encapsulate. To ensure quality, Butler Winding purchased two programmable automated testing machines. Most of our production is 100% tested on these machines.
