While bridge-type converters magnetize their transformers in both the positive and negative directions, forward-type converters magnetize them in only one direction. This suggests that in forward-type converters the magnetizing current flows in only one direction, and transformers supposedly operate only in the first quadrant of the BH plane. By determining the path followed by the magnetizing current under each operational mode of a forward-type converter, I show that these accepted theories are not necessarily correct. And by examining the behavior of the magnetizing current in two-transistor forward doubling circuit, I explain the peculiar shapes in voltage waveform.
