A general purpose, magnetically isolated current sensor is described. Based upon the flux nulling technique, this sensor uses a novel flux detector, instead of a Hall effect device, to achieve improved performance at lower cost.
This paper presents a single transistor dc-dc converter that combines both forward and flyback action. The resulting circuit is ohmically isolated and can operate over a wide range of input-to-output voltage ratios. An analysis of the circuit indicates that the forward and flyback portions of the circuit interact to produce three distinct regions of operation. With the design information presented,...
