Abstract

This invention provides a better 3 phase sensor-less permanent magnet motor control which further reduces power loss and electrical noise, and to provide a higher effective supply voltage to each winding. In order to do this the common node of a star connected 3 phase permanent magnet motor is disconnected to provide 3 separated windings and each 2 ends of the winding are driven separately by a full bridge inverter. Current flowing into each coil is sensed with analogue to digital converter to provide speed and torque information of the motor into the feedback loop. 3 phase current information is fed into the Clarke Transform of the Field Oriented Control (FOC ) or Direct Torque Control (DTC ) for close loop motor control. Replacing the Space Vector Modulation output, the 2 dimension rotational control voltages are transformed into 3 sinusoidal voltage vectors with anti-Clarke Transform, each sinusoidal voltage is then converted into Sinusoidal Pulse Width Modulation ( SPWM ) to control the full bridges. With proper configurations, the motor can also run in open loop mode.

Description

[0001] Brush less DC ( BLDC ) motor and Permanent Magnet Synchronous Motor ( PMSM ) are getting popular because of its energy saving and reliability advantage over other motors. Either sensor-based or sensor-less 3-phase BLOC/PMSM motors are commonly in star connections driven by 3 half-bridges as shown in Figure 1.
[00G2]Trapezoidal, Sinusoidal and Space Vector Modulation ( SVM } are the most common commutation methods. With 3 wire half bridge drives, the half bridge inverters try to deliver a sinusoidal current as close as possible into the windings, however this kind of 3 wire drives cannot provide best performance. Field Oriented Control ( FOC ) with SVM output is considered to be the best approach in the 3 phase sensor-less close loop motor control as shown in Figure 2, however there are 3 limitations of SVM, they are 1) floating neutral at the star common node at about 20% of the working voltage, 2) maximum use of supply working voltage is less than 100%, and 3) high harmonics on the driving current. The limitations can be improved if the standard SVM output is replaced by 3 full bridge inverters driven by Sinusoidal Pulse Width Modulation.
[0003]This invention provides a better 3 phase sensor-less permanent magnet ( BLDC or PMSM ) motor control which further reduces power loss and electrical noise, and to provide a higher effective supply voltage to each winding.
[0004] In order to do this the common node of a star connected 3 phase motor is disconnected to provide 3 separated windings as shown in Figure 3 and each 2 ends of the winding are driven separately by a full bridge inverter at show in Figure 4.
Current flowing into each coil is sensed with analogue to digital converter to provide speed and torque information of the motor as show in Figure 5. 3 phase current information is then fed into the Clarke Transform of the Fieid Oriented Control (FOC ) or Direct Torque Control (DTC ) for close loop motor control. At the output driving stage of this invention, the 2 dimension rotational voltages are transformed into 3 sinusoidal voltage vectors with anti-Clarke Transform as show in Figure 6, each sinusoidal voltage is then converted into Sinusoidal Pu!se Width Modulation { SPWM ) to control the turning on and off of the upper and lower legs on the full bridge as show in Figure 7.
