Abstract:A novel topology for the double switching forward converter is proposed in this paper, which can effectively prevent the top bridge and the bottom bridge from being short-circuited, moreover, its input voltage can be very high and the capacity of its output DC power source is large, also it can include many output groups. Therefore, this scheme is especially applicable to those electrical system of large power with high DC voltage. In addition, a novel theme to maintain and continue the flux is provided, which can effectively solve the problems existing in most of double switching forward converter when to maintain and continue the flux. Finally, the validity and application of the results of the forgoing research is verified by the analysis of the simulation waves and the results of the experiments.
Keyword:DC/DC converter, topology, self-start, PWM
