Claim Text:
1. A method for managing a current on a DC bus shared between a power management module and at least one remote inverter module, wherein, the current includes at least one harmonic component, the method comprising the steps of: sampling at a first sampling rate an amplitude of the current present on the DC bus with a current sensor; comparing the amplitude of the current sampled at the first sampling rate against a first threshold; generating a first output signal if the amplitude of the current sampled at the first sampling rate is greater than the first threshold and resetting the first output signal if the amplitude of the current sampled at the first sampling rate is less than the first threshold; sampling the amplitude of the current present on the DC bus at a second sampling rate slower than the first sampling rate; and generating a second output signal corresponding to a utilization rate of the DC bus as a function of the amplitude of the current sampled at the second sampling rate.
