Abstract :
This paper presents a systematic development of large signal and steady-state models of DC-DC parallel converter operating in continuous current mode. The models are derived by employing the well known signal flow graph method. This signal flow graph approach provides a means to directly translate the switching converter in to its graphic model, from which steady-state and dynamic behavior of the converter can easily be studied. Large signal response analysis of DC-DC parallel converter taking nonidealities of converter parameters in to account is reported and compared with PSIM simulations. Models obtained with this method are verified with the state-space averaging technique
