Creative Solutions For Complex Specifications

E Craftsmen has been designing and building Switch Mode Power Supplies for over 20 years. Understanding SMPS fundamentals is critical in optimizing transformer design to achieve:

  • Smaller Size - Cooler Operation - Lower Losses
  • Appropriate topology
  • Optimal materials – frequency dependent

Example Types of Switch Mode Transformers

  • Switching Converter
  • Flyback
  • Forward Converter
  • Push-Pull
  • Full Bridge
  • High Current
  • Buck - Boost
  • Surface Mount - Planer
