Abstract: This article proposes a novel class of impedance source networks based on coupled inductors and an active switch. Due to the turn ratio of the coupled inductors, these networks offer unique features, such as high-voltage gain and flexibility in design. The proposed networks effectively reduce the voltage spikes and current stresses, which are common drawbacks of most coupled inductor-based networks. They also offer continuous input current and ultrahigh voltage gain, minimizing shoot-through (ST) duty cycles (D) and resulting in many practical advantages. Reduced current stresses, specifically the ST current, have reduced the total power losses of the elements and the capacity of the passive elements. These features demonstrate the converters’ superior efficiency and higher power density. Theoretical performance analysis and comparisons with similar topologies are presented. Finally, experimental tests on a 300W dc–dc converter confirm the theoretical results.
