Original Abstract Submitted
a scalable battery charger can include a leader charger and at least one follower charger. the leader can include: a dc-dc converter leader phase that receives an input voltage and operates one or more switching devices to generate a regulated output; leader control circuitry that operates the dc-dc converter leader phase to regulate the output; and a leader-follower communication interface that couples the leader control circuitry to the at least one follower charger. the at least one follower charger can include: one or more dc-dc converter follower phases that receive an input voltage and operate one or more switching devices to generate a regulated output; follower control circuitry that operates the one or more dc-dc converter follower phases to regulate the follower output; and a leader-follower communication interface that couples the follower control circuitry to the leader charger.
