A new H-bridge cascaded multilevel inverter which can do regenerative action for motor drive is proposed. The proposed system adds a regenerative unit to the usual non-regenerative cascaded inverter, and the zero-sequence voltage is controlled to keep the regenerated power constant. In this case about 20% of capacitance of the rated motor power is enough for the proposed unit to decelerate motor as...
Brushless DC (BLDC) motor is attracting much interest due to good performance and ease of control for many applications. Moreover, reducing of the drive components is more attractive for low cost applications. This paper presents the design and implementation of a reduced parts BLDC motor drive using the TMS320LF2407A digital signal processor (DSP) produced by Texas instruments. Part reducing is achieved...
Principle of a new adaptive neuro-fuzzy inference system (ANFIS) with supervisory learning algorithm is introduced and is used to regulate the speed of a four-switch, three-phase inverter (FSTPI) brushless DC (BLDC) drive. The proposed algorithm has advantages of neural and fuzzy networks. To enhance of drive's performance, instead of well-known back propagation learning method, a fuzzy based supervisory...
