One of the popular impedance-network converters are Y-source converters which along with their essential characteristics such as reducing the size of converter components, single-stage power transferring, fault tolerance, and wide voltage gain capabilities there are also some drawbacks that one of the most widespread is high leakage inductances which affect performance negatively. This paper introduces a new configuration based on coupled inductors as a power electronic converter in three case studies to verify the high reliability of the proposed converter by using just a simple controller that is substantial for recycling brake energy in the propulsion system of Electric Vehicles and grid-following inverters. This topology with a straightforward structure, computation, and wide voltage gain, provides a proper connection between the components of its network that obtains appropriate paths for leakage energy, and likewise helps soft-switching in some conditions. Additionally, the performance of other previously related constructions is compared with the suggested topology. Simulations based on MATLABI SIMULINK have been carried out, and correspondingly experiment results have been also presented to substantiate the theoretical outcomes.
