Fourth Order Interleaved Boost Converter With PID, Type II and Type III Controllers for Smart Grid Applications

Summary

Switched mode power converters are an important component in interfacing renewable energy sources to smart grids and microgrids. The voltage obtained from power conversion is usually full of ripples. In order to minimize the ripple in the output, certain topological developments are made. Increasing the energy storage elements and interleaving them for 180° phase shift reduces the ripple in the circuit. This is made possible by controlling the converters using Type II and III controllers and the results are compared with PID controller. The performance is analyzed and compared in Simulink environment. Transient and steady state analysis is done for better understanding of the system.
