Abstract :
This paper examines methods for keeping the error of three phase current control inside a hexagon and to encourage transitions towards the zero error point can be achieved using only comparator information. This approach addresses some concerns of the chatter mode of simple independent phase decisions. The paper reviews options for near constant switch frequency operation.
