Abstract

This is a thesis that 100W class open frame type power module of a quarter-brick size appropriate for telecommunication is reported. The input voltage is established between 36 and 75 in range in order for power module to be utilized for the telecommunication, and output were set at 3.3V and 30A. A number of parts used for transformer, inductor, and hit sink are composed of PCB in order for DC-DC converter to be lowered below 8 mm. A constant current control circuit was annexed to the system as well as basic protection prototypes such as over-voltage, over-current, and over-temperature were well considered to enhance more credibility, and were tested. As a result, high circuit performance and credibility turned out to be significant.
