In high-power server applications to meet high-efficiency and green standards some power-supply designers have found it easier to use a phase-shifted, full-bridge converter. This is because the phase-shifted, full-bridge converter can obtain zero-voltage switching on the primary side of the converter reducing switching losses, and EMI and increasing overall efficiency. The purpose of this applicat - Gate Driver Design ConsiderationsPDF, 229 Kb, 档案已发布: Oct 10, 2016
The UCC28950/UCC28951-Q1 phase-shifted full-bridge controllers offer several features to improve power conversion efficiency at light loads. In particular, as the load current drops below the DCM threshold the duty cycle applied to the transformer reduces and eventually the device enters a burst mode. This application note describes how a user can design their gate driver circuits to operate corre - Frequency Dithering With the UCC28950 and TLV3201PDF, 386 Kb, 档案已发布: May 9, 2012

One of the key features of the UCC28950 phase-shifted, full-bridge controller is its ability to synchronize its main oscillator to an external clock source. In this way, multiple controllers can be synchronized to improve performance criteria of the end power supply. This application report expands the details of the synchronization capability of the UCC28950, provides examples of simple circuits - Pre-biased Output Voltage Startup Operation of the UCC28950PDF, 137 Kb, 档案已发布: Aug 1, 2011
