Abstract :
Magnetic materials made of iron-powder that are used for the cores of the chokes of voltage source inverters output filters significantly change their power losses and magnetic properties with the frequency and the amplitude of the choke current in the range that is important for designers. This causes the magnitude Bode plot of the VSI control transfer function to have a higher damping coefficient and the resonant frequency that differs from the theoretically calculated one. The paper shows the influence of the properties of magnetic materials on the control of a voltage source inverter. The design of the control loop that takes into account the changes in these properties is presented and tested in the experimental model.
