Abstract :
This article is based on the needs of photovoltaic solar energy generation. A new type of multilevel DC chopper with a small bulk is researched. We analyzed three-level Boost circuit, found a kind of power supply module and gave a new family of multilevel converter topology. Four-level Boost circuit has been detailed analysis. Theoretically we analyzed its work and the four levels appear rear the inductor, used a strategy of voltage control circuit and gave the control block diagram. And have done the simulation. Simulation results show the feasibility and correctness of converters.
