Abstract
Description
This article proposes a PWM-controlled dc-dc converter, similar to the traditional multilevel boost converter, which can achieve
a high output voltage with low voltage devices, and their input current is non-pulsating. Compared to the multilevel boost
converter and to other similar single-inductor single-transistor topologies, the inductor in the proposed converter drains a
reduced amount of current compared to the input current (while maintaining a continuous input current), which results in reduced
stored energy in the inductor for the same operating conditions and power rating. Theoretical analysis, simulation, and
experimental results demonstrate the benefits of the proposed converter.
