Abstract

This paper presents 50 kVA active load with low loss, which regenerate the power to utility. To make the regenerative load, 3 phase back to back inverter using DSP320C33 have been made and tested. One inverter control the power flow of the test system and the other control the regeneration of the power to utility. It could be used as a nonlinear load, resistive load, and reactive load for single phase AC, DC, three phase AC. Also, load step change and unbalanced load is simply implemented by the proposed converter. The 50 kW prototype is made and tested to verify the regenerative load function.
