Variable speed drive systems of brushless DC motors have been widely used for industry applications, home electric appliances, and so on, due to the progress of the power electronics, because of simple structure, easy maintenance, high efficiency, etc.. Moreover, because the brushless DC motor can realize the same high performance as DC motor, it is used in the fields where the high speed and h...

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...

This article presents a ground breaking traction drive for fuel cell-powered light rail vehicles based on multilevel cascade converter with H-bridge cells. The provides dc–ac power conversion unique buck–boost capability to compensate the variation of cell terminal voltage load power. In comparison conventional boost inverter, connection dc–dc and source proposed has significant benefits much s...

In this article, we have shown the possibility of improving quality energy injected into electrical network and flexibility its exchange between different components proposed hybrid (photovoltaic generator connected to network-storage battery-load DC motor) develop a control element based on combination fuzzy logic an algorithm derived from PSO Animal Behavior. The works DC/AC bi-directional DC...

this paper presents the method of reducing torque ripple of brushless dc (bldc) motor. the commutation torque ripple is reduced by control of the dc link voltage during the commutation time. the magnitude of voltage and commutation time is estimated by a neural network and optimized with an optimization method named particle swarm optimization (pso) algorithm analysis. the goal of optimization ...

This proposal proposes a DC/DC Buck Boost converter which has been used as a smooth starter for a DC Permanent Magnet Motor. In the existing system the DC/DC Buck Converter is used which provide the output less than the input Signal. Using buck converter it is difficult to increase the value of the input signal. Hence DC/DC BuckBoost Converter used from which it is possible to get both the incr...
