Abstract
A local control-unit operable as a master or a slave comprises: a memory indicative of whether the converter sub-unit is enabled or disabled; and an enable; a wake-up output; a communication link input and output interfaces configured to receive and to send master/slave information; and a further communication link input and output interfaces, configured to both enable current balancing and phase interleaving with other enabled converter sub-units; and being adapted and configured to: in response to the respective local output current being higher than a first threshold, send a wake-up request to the next converter sub-unit; and in response to (a) being a slave sub-unit; (b) the respective local output current being lower than a second threshold, and (c) receiving master/slave information indicative that the next enabled sub-unit is a master sub-unit, disabling itself. Methods of operating the same are also disclosed.
