Patent ID: 8878516

Claim:
A method for determining each current output of a three-phase inverter, comprising: supplying an initial set of control signals for the inverter for control of a load connected to an output of inverter; inspecting the initial set of control signals for the inverter; identifying a measurement conflict when at least two of said control signals are asserted within a predetermined amount of time of each other; when there is a measurement conflict, supplying a first modified set of control signals to the inverter for control of the load by shifting a position of at least one control signal related to the measurement conflict, wherein providing the first modified set of control signals comprises nullifying one of the initial set of control signals; measuring a current through a shunt resistor based on the first modified set of control signals; and supplying a further set of control signals for the inverter for control of the load dependent upon the measured current through the shunt resistor.
