Abstract :
The major differences between symmetrical topology magamps and the forward power converter magamp are discussed. In a forward power converter, a small portion of the magnetizing current of the power transformer is diverted to the secondary for reset of the magamp´s saturable reactor. In symmetrical topologies, the transformer´s magnetizing current is not used for reset of the saturable reactor(s). The magnetizing current shifts to the secondary where it causes a series of problems. The authors examine these problems, identify solutions, and explain why a half-bridge magamp power supply is inherently less versatile than the forward power converter
