Switch-controller principles

1. Input

  • PFC, passive and active

2. Converters

  • Flyback converter
  • Forward converter
  • Two transistor forward converter (= asymmetrical half-bridge)
  • Push-pull converter
  • Phase-shift converter
  • Voltage-fed push-pull (current-fed push-pull)
  • Resonant converters

3. Secondary post-regulator

  • Step-up converter (boost converter)
  • Step-down converter (buck converter)
  • Synchronous buck converter
  • Transductor regulator

4. Synchronous Rectification

  • Long experience in various kinds of synchronous rectification
  • Special transformer less drive topology invented

5. Digital Power

  • Specialized engineer focused on digital solutions
  • From simple microcontrollers to digital signal processors
  • Used from housekeeping functions to direct pulse width modulation
  • More sophisticated control algorithms are possible
  • Unprecedented design flexibility
