| Abstract |
A method of detecting current using a single shunt resistor is required for motor-drive systems in home-electrical appliances to reduce the cost of inverters. This paper proposes a method of correcting the voltage reference vector by converting coordinates from a rotating reference frame into a fixed reference frame. It also proposes a new method of transforming coordinates that is appropriate for the correction. The effectiveness of the proposed approach was confirmed through simulation and an experiment. Currents were clearly detected by using the proposed method. This demonstrated that the new method is suitable for position sensor-less drives in permanent-magnet synchronous motors. |
