Abstract

Flyback converters are widely used in several applications, however, with this topology it is very challenging to achieve high voltage operation especially with very high step-up ratio (>500) within limited space. This paper presents a new flyback-based topology which utilizes primary parallel and secondary series transformer connection in order to achieve very high step-up ratio (up to 650) as well as high voltage
operation (~2 kV) in a small volume. The topology is presented and analyzed. The advantages and disadvantages of the proposed topology are discussed. A prototype used to verify the proposed topology has been implemented. Finally, experimental results are used to validate the performance of the proposed topology.
