Design, Control and Simulation of a Non-linear-Load Current Disturbance Generator with Energy Feedback Technology

This paper deals with a high-powered, low-loss and digital current disturbance generator. It can produce harmonic current, active current, inductive reactive current and capacitive reactive current, so it is able to simulate kinds of actual industrial situations. By using energy feedback technology, the generator feeds the power consumed by the current disturbance back to the grid. Thus, it can save a lot of energy, and the lab will need less power capacity. The unit of feedback can also compensate the harmonic current and reactive current, so the generator has little impact on the power grid. Simulation result verifies the correctness of analysis and the validity of the project.
