| Summary: | A Closed loop controlled DC to DC forward converter is a requisite for the server SMPS system. High efficiency, Isolation,
Steady state voltage, Transient response, High switching frequency, reduced noises and range of steady state are all necessary
requirements for the forward converter. In this paper, a 40 V forward converter for charging the battery of server SMPS is proposed.
The proposed converter consists of a NPC-ARS circuit for soft switching on the primary side and an isolation transformer and a
rectifier structure on the secondary side. With this modified NPC-ARS circuit topology, soft switching occurs during conversion and
reduces the switching loss in this system. This paper proposed the simulation of closed loop controlled circuit, for the forward
converter with RCD snubber, double forward converter and the Modified forward converter are analyzed and discussed in this
paper. From comparison of performance in the closed loop model, a suitable converter is proposed for the sever SMPS system. The
proposed circuit achieves steady state voltage, when the disturbance occurs. A 40 V proposed circuit is designed as experimental
model to verify and compare the simulation and experimental results. This paper proposed the simulation and experimental results of
the forward converter. |
