Y-source impedance-network-based isolated boost DC/DC converter
2014 International Power Electronics Conference (IPEC-Hiroshima 2014 - ECCE ASIA), 2014A dc-dc converter with very high voltage gain is proposed in this paper for any medium-power application requiring a high voltage boost with galvanic isolation. The proposed converter topology can be realized using only two switches. With this topology a very high voltage boost can be achieved even with a relatively low duty cycle of the switches, and ...

Effects of Leakage Inductances on Magnetically Coupled Y-Source Network
IEEE Transactions on Power Electronics, 2014Coupled inductors have been used with impedance-source networks, extended from the earlier Z-source network, to keep their shoot-through times short, while providing high-voltage gains. A commonly stated requirement for these networks is that their magnetic couplings must be strong or their leakage inductances must be small.

High step-up Y-source coupled-inductor impedance network boost dc–dc converter with common ground and continuous input current is presented in this paper. The proposed converter has added auxiliary diodes and capacitors to three-winding Y-shaped coupled-inductor cells to constitute the current conduction path and realize the voltage-double function ...

Design and analysis of a quasi Y-source impedance network DC-DC converter
2017 Nineteenth International Middle East Power Systems Conference (MEPCON), 2017In this paper, performance of a high gain quasi Y-source impedance network converter is analyzed. This converter has a high voltage gain while using a small duty ratio. Compared to other impedance source converters, Y-source converter operates with lower shoot-through duty cycle for the same boosting gain.

A zero‐input‐current‐ripple high‐voltage‐gain DC‐DC converter with integrated Y‐source network
International Journal of Circuit Theory and ApplicationsSummaryThis paper proposes a zero‐input‐current‐ripple (ZICR) high‐voltage‐gain dc‐dc converter with an integrated Y‐source network. It achieves zero input current ripple by introducing a parallel branch of an extra inductor, a coupled winding, and a capacitor at the input port.
