signals. They are power amplifiers with a frequency response normally limited
to 100 Hz or below. Magnetic amplifiers use a saturable-core reactor. A
magnetic amplifier uses a RECTIFIER to solve the problem of HYSTERESIS
LOSS in a saturable-core reactor.
BIAS WINDING - allows a DC bias voltage to be applied to the saturable-core
reactor while AC control signals are applied to a separate control winding. In
this way a magnetic amplifier can be set to the proper operating point.
