Abstract
A converter for a multi-phase current network can include a plurality of current sensors, each of the plurality of current sensors being configured to detect current for a respective phase of the multi-phase network. A current averaging circuit is configured to provide an indication of the average current for the multi-phase network based on the current detected by each of the plurality of current sensors. A modulator is configured to modulate at least one phase of the multi-phase network independently of each other phase of the multi-phase network based on a difference between the current detected for the at least one phase and the average current for the multi-phase network.
