IMPROVED THE ADAPTATION FOR THREE PHASE ACTIVE FILTER UNDER NON-IDEAL-LOAD USING SAMPLE CURRENT CONTROL
Journal Title: Journal of Mechanical Engineering Research & Developments (JMERD) - Year 2019, Vol 42, Issue 3
Abstract
In this paper, a comparison between sample current control and direct current control to show the efficiency of the two current control method of Active Power Filter. The main function of the scheme was a duty by the two-level three phases inverter. According to the classic approach, transistors are converted depending on the sign of the current error, in turn, sampled at equal intervals. Both methods follow the synchronous toggle principle. In the first method, the current vector at the end of the interval is predicted for two possible cases when the operating voltage vector towards the current fault or zero voltage vector is applied. An error generates a smaller current error at the end of the selected sampling period, thus reducing the switching frequency. In the second method, the most appropriate operating voltage vector will succeed in zero vectors over the same period. A simple algorithm is used to calculate the duty cycle to achieve the smallest possible error. Both methods are simulated with three different load modes: no load, RL load, and nonlinear load. At the end of the article, the behavior of the second method, SCC, is worth more. The simulation results demonstrate the viability and effectiveness of the two technique of current control in reducing the ripple, losses, and Total Harmonic Distortion of supply current.
