SINGLE MAG AMP CONTROL SYSTEM FOR REGULATING BIPOLAR VOLTAGE OUTPUT OF A POWER CONVERTER

摘要

SINGLE MAG AMP CONTROL SYSTEM FORREGULATING BIPOLAR VOLTAGE OUTPUTOF A POWER CONVERTERAbstractA power converter embodying the principles of the invention, andhaving a positive and negative output utilizes a single magnetic amplifier controllerto control two saturable inductor cores utilized to regulate the positive and negativeoutputs by modulating the positive and negative pulse output of the power convertertransformer. The magnetic amplifier controller monitors and sums the two voltageoutputs and derives an offset from average representative output signal. This offsetfrom average representative output signal is compared with a reference signal toderive an error signal. A current responsive to the error signal is generated andutilized to periodically reset the two saturable inductor cores and regulate thepositive and negative output voltages.
