The impact of switching frequency on input filter design for high power density matrix converter

The power densities of electric power converters have increased over the last 30 years. The power density increment has been mainly achieved by a switching frequency increment of semiconductor power devices to reduce sizes of passive components. In this work, the impact of increasing switching frequency on the input filter volume is investigated in a matrix converter. A procedure is introduced for designing input filter of matrix converter with minimum volume by taking to account power quality standard requirements. Experimental results show the effectiveness of designed input filter.
