The practical limits on the maximum modulation depth are considered for two level converters with space vector PWM. Maximum modulation depth is analysed as a function of minimum pulse width and deadtime compensation. A method is presented whereby the deadtime compensation algorithm naturally leads into pulse dropping for the non-currentcarrying device. The proposed method is analysed and test results from a 3MW industrial drive are presented.
