Abstract :
Detailed analysis and optimum design of the commutating circuit of the recently proposed DC-side commutated current-source inverter are given. Analysis was performed for each topology mode during a step transition interval under certain assumptions and using various normalised quantities. Using the analysis results, optimum design of the commutating circuit was studied with an aim to maximising the turn-off time with a minimum commutating energy. Experimental results showed reasonably good agreement with the theoretical results.
