Abstract
A power converter embodying the principles of the invention, and having a positive and negative output utilizes a single magnetic amplifier controller to control two saturable inductor cores utilized to regulate the positive and negative outputs by modulating the positive and negative pulse output of the power converter transformer. The magnetic amplifier controller monitors and sums the two voltage outputs and derives an offset from average representative output signal. This offset from average representative output signal is compared with a reference signal to derive an error signal. A current responsive to the error signal is generated and utilized to periodically reset the two saturable inductor cores and regulate the positive and negative output voltages.
