- U-154 The New UC3879 Phase-Shifted PWM Controller Simplifies the DesignPDF, 274 Kb, 档案已发布: 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 UC3875PDF, 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 - DN-63 The Current-Doubler Rectifier: An Alternative Rectification TechniquePDF, 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 - 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 DoublerPDF, 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 - Current Doubler Rectifier Offers Ripple Current CancellationPDF, 116 Kb, 档案已发布: Sep 21, 2004
