    Abstract
  • The concept of connecting two boost half bridge DC-DC converter modules in input-parallel output-parallel configuration is presented. The input-parallel-output-parallel (IPOP) converter consists of multiple boost half bridge (BHB) DC-DC converter modules which are connected in parallel at the input and output side. This kind of converter is an attractive solution for high power applications. The correlation between input current sharing (ICS) and output current sharing (OCS) of the IPOP converter basic modules is described. Two loop control strategies, consisting of input current loop and output voltage loop, have been developed to achieve equal ICS and OCS in this present work. The control strategy for the IPOP configuration of boost half bridge DC-DC converter has been verified for different load conditions (half load and full load). The IPOP system proposed here is comprising of two modules but it can be extended to three or more. The performance of the proposed system along with the control strategy is verified by simulation in MATLAB using Simpower tool. Finally the satisfactory simulation results are obtained.
