Abstract: This paper presents a multilevel DC-DC boost converter (MBC). It is derived from a conventional boost converter just by adding (2N-1) number of capacitors and same number of diodes in order to obtain N levels of output voltage. Its key feature is to convert low input DC to a high output DC at various levels. This feature makes it a suitable candidate for renewable applications like photovoltaic (PV) system, fuel cell system etc. This paper presents a mathematical model of a N level boost converter. Effect of series resistance (ESR) in inductor is analyzed. A closed loop system for a three level MBC is developed and corresponding simulation results are presented.
Keywords: Multilevel DC-DC boost converter (MBC), PV system, fuel cell system, ESR.
