Abstract

In this work, an isolated DC/DC two-inductor boost converter is proposed. The topology is able to start up and operate in steady-state at any output level within 0V to 400V. The current and voltage characteristics make this topology suitable for applications where the relationship between input current and output voltage is too long, such as applications in hybrid electric vehicles (HEVs). In order for its operation to be possible at any output level, two auxiliary windings were added. These auxiliary windings were included to ensure that the startup current does not rise to a higher level, as opposed to other isolated boost converters where the start-up current level is high. The design of the converter and a detailed analysis are given; an experimental 200W prototype is presented to validate the converter operation and its design.
