Voltage-Double Magnetically Coupled Impedance Source Networks

A family of voltage-double magnetically coupled impedance source networks is presented. The scheme of the proposed family is that adding the auxiliary capacitors and diodes to the magnetically coupled transformers to realize the voltage-double function. The proposed impedance networks can produce the higher voltage gain, reduce the voltage stresses across the passive components, have a common ground, realize the continuous input current, and suppress the start-up inrush current. Finally, one of the resulting topologies is verified in the condition of dc-dc converter and dc-ac converter, theoretical analysis and experimental results are offered to verify the topology's validity.
