Theory of 3-phase bridge magnetic amplifier: I -Steady state

The primary object of this paper is to develop a theory for the 3-phase bridge magnetic amplifier. A further object is to describe the utilization of this theory to arrive at design and performance equations which are sufficiently simple and accurate for engineering purposes. Part I deals with the steady-state operation, and Part II (which is planned for future publication) with the transient performance. Because of space limitations, the full description of the circuit components has been relegated to Part II.
