Enhanced Conversion Ratio and Components Stress Mitigation of Interleaved DC-DC topology using Integrated Control Strategy

چکیده مقاله

Due to the limited and fluctuating nature of renewable energies, high-gain dc converter with high power transmission is essential requirement for using this energy. This paper provides an integrated control strategy (ICS) for optimization of the high-gain interleaved DC-DC converter. However, the multi-level dc-dc converter suffers from high power transfer and high switch stresses, which extremely limits the conversion ratio and system performance. To address this concern, the effective high-gain interleaved boost converter with ICS produces higher conversion ratio with low switching ripple, which directly reduces the switching losses on the semiconductors, that cusses to increase the efficiency of the system. By unifying convenient of current sharing factor (CSF) can be establishes the same current for all phases to transfer the same power in each phase. The ICS allows to use multi-level interleaved (expandable to a higher number of phases) with low ripple strokes under variable renewable sources, along with phase-shift and frequency modulation control capabilities. A variety of simulation results are presented to verify the theoretical findings. Finally, a 55 V input, 220 V output prototype with a 2Kw output power rating is implemented to validate flexibility and effectiveness in various mode operation of ICSCM.
