Programmable alternating current (AC) load having regenerative and dissipative modes

A programmable alternating current (AC) load in communication with an equipment under test (EUT), the EUT generating an equipment under test voltage, the programmable AC load comprising:

• an active load profiler (ALP) creating current modulation load profiles sent to the EUT, the ALP comprising:
• a voltage source inverter having an AC side and a direct current (DC) side, the AC side of the voltage source inverter in communication with the EUT for receiving the equipment under test voltage;
• and
• a control module in operative communication with the voltage source inverter of the ALP, the control module sending a control duty signal to the voltage source inverter indicating a switching frequency and a duty cycle of the current modulation load profiles;
• a grid-connected inverter having an AC side and a DC side, the DC side of the grid-connected inverter in communication with the DC side of the voltage source inverter of the ALP, the grid-connected inverter providing a regulated DC voltage source to the voltage source inverter of the ALP;
• and
• an operational mode selector in communication with the AC side of the grid-connected inverter, the operational mode selector placing the programmable AC load in either a regenerative mode where the equipment under test voltage is sent to a main grid or a dissipative mode where the equipment under test voltage is dissipated by heat.
