Abstract :
A novel pulsewidth modulation buck-boost AC chopper using regenerative DC snubbers is proposed and analyzed. Compared to the previous buck-boost AC choppers, AC snubbers causing power loss are eliminated using regenerative DC snubbers. Experimental results show that the proposed scheme gives good steady-state performance of the AC chopper, which coincides with the theoretical results
