Abstract
This paper presents a high gain non isolated Multilevel Cascaded Boost Converter (MCBC) for Electric vehicle applications. The proposed converter associates the basic cascaded Boost converter along with multilevel boost converter for boosting the voltages generated from different sources like solar energy, fuel cell and Battery. The multilevel boost converter is intended to be utilized as a dc link in which the high gain boosted voltage is provided to the multilevel inverter. By expending a single driven semiconductor switch and an inductor, the proposed converter is capable of producing high voltage gain with continuous input current and much higher step up conversion ratio. It not only allow to operate at much higher frequencies but aids in operating with a minimum duty cycle without a transformer. The proposed converter with five cascaded levels are simulated and is verified experimentally. The results thus illustrated go in concurrence with each other.
