Patent attributes
The present invention relates to a multi-output current-balancing circuit, which in one embodiment can include: (i) a transformer having a primary winding and a plurality of secondary windings, where the primary winding receives an AC input current; (ii) a plurality of first and second rectifier circuits and a plurality of first current balancing components, where each of the first and second rectifier circuits and the first current balancing components is coupled to a corresponding secondary winding, where each the first current balancing component is configured for current balancing between each of the first and second rectifier circuits of the corresponding secondary winding; and (iii) at least one second current balancing component, where each second current balancing component is coupled to a pair of the second rectifier circuits that correspond to different secondary windings, where the second current balancing components are configured for current balancing between different the secondary windings.
