APARATO PARA CONTROLAR UN INVERSOR.

摘要

The apparatus for controlling an inverter is disclosed which detects a rotation angle of a load using a current supplied to the load when the inverter utilizes a voltage/frequency control to control the driving of the load, and accurately drives the load using the detected rotation angle, where the current supplied to the load by the inverter is detected by a current sensor, and a rotation speed of the load is estimated by the detected current to be used for the driving of the load.
