“…Ertuğrul N et al (1994) [7] stated that the rotor position information can be obtained without using a sensor with the voltage and current signals received from a brushless direct current motor. Singh (1997) [8] investigated the effects of permanent magnet brushless direct current motors on the reduction of torque ripple, semiconductor power electronics, and microcontrollers on cost reduction and possible future applications.…”

“…Here, a sensor-less control strategy is employed, that minimizes the overall bulkiness, volume and price of the drive system. A zero crossing detector (ZCD) is used to sense the instant each time the EMF in the un-energized phase passes through zero [10][11][12][13]. At this juncture, the back-EMF can be measured, and it crosses zero [12].…”

This paper details an Integrated Single-stage converter fed sensor-less BLDC motor drive. The drive speed is regulated by altering the DC voltage of the inverter that drives the motor. The switches of the inverter are operated at the line frequency, thereby reducing the inverter switching stresses and enhancing the overall drive system efficiency. The converter works in Dual-discontinuous Current Mode (D-DCM) for Power Factor Correction (PFC) and better power quality at the supply mains. DC voltage control is used adjust the duty ratio of the converter switch. Fast voltage regulation, zero current switching at turn-on and enhanced power factor for a broad range of speeds are the advantages of this converter configuration. The necessity of Hall-Effect position sensors is eliminated by employing a sensor-less technique for brushless dc motor commutation. This reduces the dimensions, volume and expenditure of the motor drive and upgrades its overall efficiency. Drive performance is assessed over an extensive span of speeds. A power factor approximating to unity, and enhanced power quality indicators which are adequately within the sanctioned cap of IEC standard 61000-3-2 are obtained.

ABSTRACT:In this paper proposes a simple but effective method of electric brake with energy regeneration for a brushless dc motor, of electric vehicle (EV). BLDC motor control utilizes the traditional proportional-integralderivative (PID) control and the distribution of braking force adopts fuzzy logic Conventionally, EVs use mechanical brake to increase the friction of wheel for the deceleration purpose. However, from the viewpoint of saving energy, the mechanical brake dissipates much energy since the EV's kinetic energy is converted into the thermal one. In view of this, this paper discusses how to convert the kinetic energy into the electrical one that can be recharged to the battery. Thus, both the electric brake and energy regeneration are achieved. In comparison to other solutions, the new solution has better performance in regard to realization, robustness and efficiency. In this paper, we have chosen the three most important factors: SOC, speed and brake strength as the fuzzy control input variables. We have found that RBS can obtain appropriate brake current, which is used to produce brake torque. At the same time, we have adopted PID control to adjust the BLDC motor PWM duty to obtain the constant brake torque. PID control is faster than fuzzy control so the two methods combined together can realize the smooth transition since the braking kinetic energy is converted into the electrical energy and then returns to the battery, the energy regeneration could increase the driving range of an EV.
