INVERTER CURRENT MEASUREMENT USING SHUNT RESISTOR

摘要

A method for determining each current output of a three-phase inverter (102) comprises the following steps: inspecting an initial set of control signals for the inverter (102); identifying a measurement conflict when at least two of said control signals are asserted within a predetermined amount of time of each; if there is a measurement conflict, providing a first modified set of control signals to the inverter by shifting a position of at least one control signal related to the measurement conflict; and measuring a current through a shunt resistor based on the first modified set of control signals. Also, an electronic device and a digital processor (DSP) for determining each current output of three-phase inverter (102) are provided.
