Partial Resonant-based Soft-switched Current-fed DC-DC Converters
High-frequency power conversion has been a subject of high interest to design and realize high-density, lightweight, and cost-effective power electronic converters. However, hard switching of semiconductor devices leads to increased switching power losses limiting their utilization to their full capacity and compromising on efficiency. Soft-switching techniques have been introduced for many years to elevate the device switching frequency while reducing/eliminating the switching losses to promote the high-frequency power conversion. Soft-switching can be obtained by several methods and that introduced different design constraints and limitations on soft-switching as well as power converter performance. Resonant converters are popular but offer challenges in voltage gain applications. Additionally, resonant converters suffer from low partial load efficiency owing to circulating current at light load conditions. Other crucial challenges are frequency modulation for load voltage regulation and power flow control, and immunity to resonant current variation with reduction in load current. Partial resonance converters allow resonance only during the switching transition (on and off) that is less than 20% of the switching cycle. This improves light load efficiency and reduces the circulating current through the components reducing their kVA ratings.
