High Conversion Ratio Multiphase Boost Converter With Dynamic Charge Equilibration for Bipolar Outputs
This article proposes a multiphase bipolar-output hybrid (BOH) converter designed to achieve a high conversion ratio, minimal output ripple, and enhanced efficiency. By incorporating a dynamic charge equilibration (DCE) mechanism, the proposed converter reduces parasitic switching losses by 26%. The DCE driver employs LC resonant charge-recycling, effectively reusing stored charge and minimizing switch delay. Furthermore, the DCE replica technique ensures balanced charge distribution, even under challenging load transients. Experimental results demonstrate the superior performance of the multiphase BOH converter, achieving a peak efficiency of 95.7% at VIN = 4.5 V and 93.2% at VIN = 3.3 V, while supporting load currents up to 1.5 A. Additionally, the converter exhibits low output ripple, with less than 2 mV for the positive output and 3 mV for the negative output.
期刊介绍：
The IEEE Transactions on Power Electronics journal covers all issues of widespread or generic interest to engineers who work in the field of power electronics. The Journal editors will enforce standards and a review policy equivalent to the IEEE Transactions, and only papers of high technical quality will be accepted. Papers which treat new and novel device, circuit or system issues which are of generic interest to power electronics engineers are published. Papers which are not within the scope of this Journal will be forwarded to the appropriate IEEE Journal or Transactions editors. Examples of papers which would be more appropriately published in other Journals or Transactions include: 1) Papers describing semiconductor or electron device physics. These papers would be more appropriate for the IEEE Transactions on Electron Devices. 2) Papers describing applications in specific areas: e.g., industry, instrumentation, utility power systems, aerospace, industrial electronics, etc. These papers would be more appropriate for the Transactions of the Society which is concerned with these applications. 3) Papers describing magnetic materials and magnetic device physics. These papers would be more appropriate for the IEEE Transactions on Magnetics. 4) Papers on machine theory. These papers would be more appropriate for the IEEE Transactions on Power Systems. While original papers of significant technical content will comprise the major portion of the Journal, tutorial papers and papers of historical value are also reviewed for publication.
