Arifin Wibisono, a graduate student at Diponegoro University’s Master of Electrical Engineering program, creates a control strategy for a multiphase bidirectional DC/DC converter. Arifin Wibosono is supervised by Dr. Iwan Setiawan and Mochammad Facta Ph.D. The research’s primary goal is to demonstrate analytical and practical digitalization implementation of average current control methods with DSCs (Digital Signal Controllers). In DC Microgrids, the bidirectional DCDC converter is crucial as a charge and discharge controller connecting the ESS (Energy Storage System) in both islanding and grid-tied modes. Low-cost 16-bit DSCs were used to design and incorporate codes for typical contemporary control algorithms.
In order to produce a discrete model in this format, a bilinear transformation is required. The average current control approach with a closed loop proportional-integral algorithm yields more consistent noise control, does not need slope compensation, and does not introduce an error in the peak current value to the average current value. Current ripple can be minimized and reduced by using multiphase interleaved topologies. The efficiency of the DC Microgrids system will be increased by regulating the current on the DC-DC Converter, which will have an effect on the power flow during the charged-discharge process. The results of the analysis, modeling, simulation, hardware implementation, and laboratory testing demonstrate that this technique can better manage the current.
