Reconstruction

Voltage reconstruction in inverter

This paper presents a simple current sensing and reconstruction scheme for a VSI (Voltage Source Inverter) with three shunt resistors. Using the shunt resistors, the actual current can be detected during the turn-on region of the bottom-side switches. The NEIC-SHIVR method takes into account not only the influence of non-linear errors in. . This software module calculates three phase voltages impressing to the 3-ph electric motor (i.
