  U-154 The New UC3879 Phase-Shifted PWM Controller Simplifies the Design
  PDF, 274 Kb, Datei veröffentlicht: Sep 5, 1999
  This application note introduces the UC3879 integrated circuit and compares its performance to that of its predecessors, the UC3875/6/7/8 controller family. These integrated circuits provide all necessary control, decoding, protection, and drive functions to successfully manage the operation of the full-bridge converter with phase-shifted control. This integrated solution greatly simplifies the de

  A Comparison Between the BiCMOS UCC3895 Phase Shift Controller and the UC3875
  PDF, 21 Kb, Datei veröffentlicht: Feb 22, 2001
  This application report compares the BiCMOS UCC3895 to its bipolar predecessors, the UC3875/6/7/8 family and the UC3879 controller. All of these integrated circuits provide the control and drive signals needed to implement a full-bridge converter using phase-shifted control. The UCC3895 represents the latest offering in the Texas Instruments line of phase-shift controllers, incorporating a feature

  DN-63 The Current-Doubler Rectifier: An Alternative Rectification Technique
  PDF, 81 Kb, Datei veröffentlicht: 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, Datei veröffentlicht: 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

  Synchronous Rectifiers of a Current Doubler
  PDF, 207 Kb, Datei veröffentlicht: Feb 27, 2003
  Driving a current doubler synchronous rectification output stage can be a very complex task, especially for a phase shifted full bridge topology. However, using the A and B outputs of the UCC3895 along with the UCC37324 dual 4-A MOSFET driver, direct PWM control of a synchronous rectifier current doubler output stage achieves. This technique provides the proper gating and timing signals necessary
