Abstract: This paper presents the removal of initial phase transient currents in an existing dc-dc boost converter topology with the help of a modified switched inductor cell. In an earlier proposed topology, a novel single switch boost converter was proposed with high voltage gain, which however gave a high initial transient current of the order of 26kA on simulating in MATLAB Simulink environment. This initial phase current was removed by placing a small valued inductor and a freewheeling diode in series with boost capacitor. The inductor is placed in parallel with the diode and creates an open circuit initially, this arrangement limits the current to a bearable value, i.e. approximately 180A, without compromising with the high gain of the cell. The results of the proposed modifications are validated using MATLAB Simulink.
