Research On The Application Of The Planar Integrated Magnetics In The Current-Doubler-Rectifier ZVS PWM Full-Bridge Converter

In this thesis, the application of Planar Integrated Magnetics isinvestigated in the Current-Doubler-Rectifier Zero-Voltage-Switching PWM Full-Bridge converter. The operation principle of the convert-er isanalysed in detail, design result and select means of element parameters of the converter are given. In order to reduce the loss and improve power density of the converter, the losses of the swit-ching are evaluated to find out the distribution of losses.Two tapes of Integrated Magnetics are given in the converter, that is the tape of the two inductors integration and the tape of thetwo inductors with the one transformer integration. Waves of the main element parameters and efficiency curves with Discrete Magn-etics and Planar Integrated Magnetics of the converter are given bycircuit simulation software with Ansoft Simplorer 6.0, which provesthat core size and loss can be reduced and power density and effi-ciency can be improved with Planar Integrated Magnetics.
