A solar pumping model is proposed in this paper using a Brushless DC (BLDC) motor. Zeta converter used as DC-DC link between the voltage source inverter and PV array. enables soft starting of BLDC motor speed control achieved by simple variation voltage, thereby eliminating need for complex switching circuitry. belongs to class buck-boost hence offers wide range operating voltage. The cost-effe...

In this paper, an integrated model of the human circulatory system with a brushless DC axial flow ventricular assist device (VAD) was developed. The resulting nonlinear hybrid model is then used to design the VAD feedback control system. The VAD controller is designed to maintain a physiologically motivated perfusion; it is tested using computer simulations of different scenarios ranging from t...

The main purpose of this paper is to describe the four-switch brushless dc (BLDC) motor drive for varoius applications. For effective utilization of the developed system, a novel direct current controlled pulse width modulation scheme is designed and implemented to produce the desired dynamic and static speed–torque characteristics. Also, t h e feasibility of the four-switch converter. Keywords...

The Permanent Magnet Brushless DC (BLDC) motor offers higher efficiency, low maintenance, reduced weight and compact construction. For many industrial applications, the BLDC motor is increasingly being used. This paper presents a new sensorless drive scheme for BLDC motor based on the back EMF difference. The commutation point of the drive is determined by detecting the Zero Crossing Point (ZCP...

Using a top-down design methodology, two levels of hybrid electric vehicle power system are presented in the paper. At the highest abstraction level, a behavior modeling method is used to develop models for 3-phase AC/DC converter and brushless DC motor controller, which reduce the simulation time without compromise of accuracy. At the second level of design, six diodes along with delta-delta a...
