ABSTRACT:
A method of modeling a response of an inverter having a pair of switches which are alternately operated to alternately connect first and second voltages to an inverter output to develop an inverter output voltage includes the steps of assuming the inverter output voltage is substantially at or between the first and second voltages during a dwell interval and modeling the inverter response based upon such assumption. The modeling may be used as part of a control strategy for an inverter wherein output harmonic content is minimized.
