A Comparative Analysis of PID and SMC Control Topology for the Two Phases Interleaved DC DC Converter

The topology of a bidirectional DC-DC converter is typically crucial in systems that require the bidirectional exchange of electricity. It is frequently used in composite energy storage and microgrids. Electric cars, systems, etc. The architecture is interleaved to increase power handling capability and decrease input side ripple current. By allowing current sharing between several phases, interleaving improves the converter’s power density by allowing for a smaller filter inductor and input and output capacitors. An N-phase non-isolated bidirectional DC-DC converter’s design and generalized phase shift specifications are presented in this publication. In MATLAB/Simulink, a two-phase non-isolated interleaved bidirectional DC-DC converter’s closed-loop simulation is performed while taking into account both the boost and buck modes of operation. The outcomes demonstrate equitable current sharing between phases, which lowers input current ripple, reduces the size of filter elements, and enhances converter thermal distribution. When integrating with non-isolated DC-DC converters in power systems, control strategies like proportional integral derivative (PID) and slide mode control (SMC) are also examined in terms of the parameters settling issue, response time, and complexity.
