DC TO DC CONVERTER WITH VOLTAGE REGULATION THROUGH PULSE WIDTH MODULATION BY CONTROL OF THE DISTRIBUTION OF FLUX VARIATIONS IN A DUAL CORE TRANSFORMER

摘要

A DC to DC converter regulates its voltage output by controlling the distribution of flux variations in a dual core transformer included in the converter's inverter circuit. The inverter output is coupled to a rectifier and the output load, via one core of the transformer. A voltage regulation control circuit includes the other core of the transformer and pulse width modulates the inverter output by controlling the flux variations in the two cores of the transformer. The second core included in the voltage regulation control circuit advantageously permits complete isolation between the input and output circuits of the converter.
