应用须知

  • A Comparison Between the BiCMOS UCC3895 Phase Shift Controller and the UC3875
    PDF, 21 Kb, 档案已发布: 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
  • Phase Shifted Full Bridge, Zero Voltage Transition Design Considerations (Rev. A)
    PDF, 393 Kb, 修订版: A, 档案已发布: 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, 档案已发布: 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

  • DN-63 The Current-Doubler Rectifier: An Alternative Rectification Technique
    PDF, 81 Kb, 档案已发布: 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
