Abstract

Traditional PI controllers can have poor regulation performance due to steady state errors when tracking sinusoidal signals. Hence synchronous PI controllers are often used, although this controller requires reference frame transformations. In this paper, a modified PI controller, which uses current feedforward, is developed to control the output currents of a matrix converter. The controller is implemented in the natural frame (abc) together with space vector modulation. The output current is then controlled. This controller does not require any frame transformation and it demonstrates improved steady-state tracking performance. The total harmonic distortion is improved at the same time. A constant switching frequency is maintained because of the application of the modulation stage. Simulation results verify the feasibility and effectiveness of the proposed controller.
