Soft Commutated Three-Phase Dc-Dc Converter
High efficient DC-DC Converters find its application in electric power generation, transmission, distribution and
Uninterruptable power supplies (UPS). Three phase converter system as compared with single phase converter system
increases power density with reduced switching stresses, efficient usage of the transformer magnetic core and smaller filter
design as the frequency of the system is higher. Inorder to make use of the above mentioned advantages a ZVS-PWM three-
phase current-fed push-pull dc-dc converter with active clamping was developed. This converter topology allows the reuse of
the energy from the leakage inductances and reduces the electromagnetic interferences (EMI). The topology was designed and
simulated using MATLAB/SIMULINK. The input supply voltage used for the converter is 120V DC.
