Abstract
A method of controlling dissipation of regenerated power in a multi-channel drive system having a plurality of inverters connected in parallel across an input power supply to drive one or more loads via one or more motors. The method includes determining a circulation current demand for the inverters when the drive system is operating in regenerative mode, the circulating current demand being dependent on the regenerated power and applied to the inverters such that the regenerated power flows through the inverters and is dissipated by the inverters.
