Abstract


The current paper presents the Direct Torque Control (DTC) methods, implemented in six-switch inverter for brushless DC (BLDC) motors with non-sinusoidal back electromotive force, by using two-phase conduction modes. Then, the proposed two-phase conduction mode for DTC of BLDC motors in constant torque area is introduced.  In this control method only two phases  conduct  using a six-phase inverter at any moment of time. Choosing the spatial vectors of inverter voltage in two-phase conduction mode appropriately, the current with a desired waveform is obtained by a simple look-up table. Thus, it is possible to obtain the DTC of a BLDC motor drive with a faster torque response. In this paper, the modeling and simulation of direct torque control and direct flux control with Hall Effect sensor and non-sinusoidal back electromotive force are extensively examined by using a three-phase conduction method and a six-switch inverter.
