摘要

One way to achieve high bandwidth current control is the use of high switching frequencies. Drawbacks are higher switching losses which decrease the drive efficiency and increase heat sink size and semiconductor cost. This contribution describes how model based control can be used in a very resourceful way by utilizing a Luenberger Observer in conjunction with current prediction to enable high bandwidth current control at lower and therefore more energy efficient switchina freauencies.
