Resumen:

A novel DC-DC power converter has been developed to fulfill the requirements of a solar electrical propulsion module. The maximum power point tracker solar array regulator is divided into two series converters; a direct-energy transfer (DET) regulator and a secondary step-up converter. The DET regulator creates an unregulated maximum power point bus and the secondary converter regulates to a 100-V bus. The purpose of this paper is to describe the solution with a specific design and experimental results.
