​Abstract
In this paper presents implementation of high-efficiency non-isolated three-stage interleaved soft switching boost converter on-board battery charger (OBC) for high voltage applications. A suitable circuit structure is determined to charge a battery in a wide spectrum of input and output conditions. The input voltage is rectified from AC to DC then DC voltage is boosted using three phases interleaved cascade boost converter. Reviewing the comparing circuit topologies, the two phases interleaved cascade buck-boost converter having buck unit and boost unit. The buck converter switches are connected in series and the boost converter switches are connected in parallel on the circuit. In this paper we have use only boost converter, so not having isolation problems. A detailed theoretical analysis, operating strategy, simulation and hardware results are presented in order to evaluate the performance of the system.

​​Keywords: Interleaved Cascade boost converter; Electric vehicles; Nonisolation; On-board battery charger.
