Abstract
An interface between software and hardware, as well as a fuzzy logic control algorithm, for controlling a DC-DC converter or an AC-DC or DC-AC inverter are provided. A control circuit receives commands from a control logic to operate a converter or inverter in various operation modes. Control software inputs can be translated into signals to operate the converter or inverter. Control variables in the control software can be configured to operate under various control modes. If the converter or inverter cannot simultaneously meet the demands placed on two or more variables, the control logic can use prioritization to choose a more important constraint.
