In the present scenario, the renewable energy sources solar and wind are used locally by creating a Nano grid. In the integration of these sources to the Nano grid, hybrid converters play an important role to provide both AC and DC loads. Existing hybrid converters suffer with limitations such as no protection for shoot through condition and separate converters are used to supply AC & DC loads, which increases the size and cost of the system. A boost derived hybrid converter which provides both AC and DC output has overcome the above limitations. Further, this converter operation is unstable under unbalanced loading conditions and also its boost gain is low. To improve the performance of boost derived converter the proposed work presents a SPWM scheme based boost derived hybrid converter. The proposed hybrid converter is modeled in MATLAB/PLECS Simulink and its performance is verified under no load and different loading conditions. A laboratory hardware model is developed to validate the Simulink model results. It has been observed that both laboratory model results and Simulink model results are in good agreement with each other. It has been seen that boost derived converter with SPWM scheme has performed better than the PWM based converter.
