Abstract
The paper reports on research aimed at achieving the computer-control of power electronic converters for high power applications. Hitherto, in motor drive applications, the four-timer method has been adequate in approximating the sinusoidal pulse width modulation (SPWM) strategy for microprocessor control. This paper shows that the ideas of the four-timer method can be extended, with modifications, to the multi-module arrays of power converters which will be required to meet high MVA ratings. Simulation and experimental results have shown that the resultant seven-timer method can implement the linear SPWM strategy for multi-converters
