Research on Three-Phase Energy-Feedback Type Electronic Load of Current Hysteresis Loop Control

This paper proposes an Energy-Feedback Type electronic power load that can run with the same function as resistors in the test of all kinds of DC power source. The power load can be regards as a resistor whose value changes smoothly. It transforms the DC power into AC power and then sends it into the utility power system. This paper analyses the system configuration and operation principle of electronic power load and its control method. Experimental results verify that the electronic power load is well des...
