| Abstract |
An adaptive overmodulation method for space vector modulation (SVM) controlled matrix converter is presented in which the linear, sinusoidal operation range is continually optimised to achieve the highest possible voltage transfer ratio with minimum harmonic distortion. A maximum linear modulation index between the theoretical limit of 86.6% and unity is achievable, depending on the frequencies of the input and output voltages and their phase angles. Simulated and experimental results under various operating conditions are given, showing voltage transfer ratios of 0.97 to 0.997 with harmonic distortion levels of less than 2%. |
