Fast Acting Regenerative DC Electronic Load Based on a SEPIC Converter

A fast acting regenerative dc electronic load based on the single-ended primary inductor converter (SEPIC) converter has been implemented. A simple multiloop feedback control system has been design for the SEPIC converter to realize the main function of electronic load. Instead of discharging via resistive load, the output of the converter is connected to rechargeable batteries such that discharged energy can be saved for future use. Circuit implementation of the proposed scheme is presented and experimental results are included to demonstrate the effectiveness of the proposed design.
