Application Notes

  • DN-63 The Current-Doubler Rectifier: An Alternative Rectification Technique
    PDF, 81 Kb, File published: Jan 12, 2001
    The UC3875, UC3879, and UC3895 families of ICs control a bridge power stage by phase-shifting the switching of one half-bridge with respect to the other. This method allows constant-frequency pulse-width modulation in combination with resonant, zero-voltage switching for high efficiency performance. These ICs can be configured to provide control in either voltage mode or current mode operation, wi
  • Phase Shifted Full Bridge, Zero Voltage Transition Design Considerations (Rev. A)
    PDF, 393 Kb, Revision: A, File published: Jan 22, 2011
    This Application Note will highlight the design considerations incurred in a high frequency power supply using the Phase Shifted Resonant PWM control technique. An overview of this switching technique including comparisons to existing fixed frequency non-resonant and variable frequency Zero Voltage Switching is included. Numerous design equations and associated voltage, current and timing waveform
