| Abstract: | Multi-modular system plays an important role in power system architecture because low voltage and low power converters can be connected in any combination parallel or series at input/output side in order to obtained any given power system specifications. Multi-modular boost half bridge DC-DC converter in the configuration of input series output parallel has been investigated in this paper. The boost half bridge DC-DC converters are connected in input series output parallel configuration in order to achieve equal input voltage sharing and output current sharing between the converters. This can be achieved with the help of dynamic control scheme which consists of two loops, a voltage loop and a current loop, for each module. Dynamic behavior of multi-modular converter configuration has been observe by varying the load condition. Moreover, the results obtained through multi-modular converter describe that the system has good dynamic and steady state response. Although two converter modules are focused in this paper but it can be modified to any number of modules. |
