This paper presents the closed loop control of a high voltage gain IBC. A high voltage gain Interleaved Boost Converter (IBC) with Voltage Multiplier module is suitable for renewable energy system, which requires high step up conversion ratio. In order to obtain high gain, a built-in transformer and a voltage multiplier module inserted into each phase of conventional interleaved boost converter. The voltage multiplier cell is composed of built-in transformer windings, diodes and small capacitors. The Voltage multiplier module is efficient, low cost and simple topology composed of switched capacitors and diodes to obtain high DC output voltage. In order to obtain the controlled output voltage from a DC – DC converter under varying input conditions, it is necessary to regulate the output voltage which is achieved through closed loop control. A PI controller is implemented to improve its performance of the proposed IBC during the disturbances due to renewable energy sources. The closed loop control of the proposed IBC with multiplier module is analyzed and simulated for high voltage gain using MATLAB Simulink.
