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.

一种用于多电平逆变器应用的新型非隔离式单开关多电平级联 DC-DC 升压转换器

本文介绍了一种用于电动汽车应用的高增益非隔离多级级联升压转换器 (MCBC)。所提出的转换器将基本级联升压转换器与多电平升压转换器相关联，用于提升太阳能、燃料电池和电池等不同来源产生的电压。多电平升压转换器旨在用作直流链路，其中向多电平逆变器提供高增益升压电压。通过使用单个驱动半导体开关和电感器，所提出的转换器能够产生具有连续输入电流的高电压增益和更高的升压转换比。它不仅允许在更高的频率下运行，而且有助于在没有变压器的情况下以最小占空比运行。所提出的具有五个级联级别的转换器进行了仿真并通过实验进行了验证。如此说明的结果彼此一致。
