The development and design of a bi-directional pulse-current sensor for bi-directional PWM dc–dc converters are presented. The bi-directional sensor consists of functionally two unidirectional sensors. However, instead of using two separate transformers, an integrated magnetic component, which functions as two pulse-current transformers, is used. The z-parameter (gyrator) model and the equivalent-circuit model of the integrated transformer are derived. Based on the equivalent-circuit model, some design criteria of the integrated transformer for the bi-directional pulse-current sensor are described. Simulated and experimental results have proved the usefulness of the bi-directional pulse-current sensor.
