DN-63 The Current-Doubler Rectifier: An Alternative Rectification Technique
PDF, 81 Kb, Archivo publicado: enero 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, Revisión: A, Archivo publicado: enero 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
