Advanced Drive System for DC Motor Using Multilevel DC/DC Buck Converter Circuit

Application of DC/DC Buck Power Converter in DC Motor for Speed Controlling Using PI Controller

DC motor widely used-high precision digital controls. Speed control of dc motor is achieved with smooth starter by using buck converter. Hard switching causes unsatisfactory dynamic behaviour produces abrupt variations in the V & I of the motor overcome by dc-dc buck power converter by PI controller. A separately excited dc motor is used for this simulation. The proposed system with PI control ...

Simulation Model of Buck Converter Closed System Using PMBLDC Drive

The PMBLDC motor is 3 phases, 4 poles, Y connected; trapezoidal back-EMF type of BLDC motor for automotive industry application is modeled and simulated in MATLAB / SIMULINK. A MATLAB program is developed to simulate the overall motor drive system. A closed loop speed control strategy is developed and simulated. The drive system is proposed with a buck converter topology. In this model the buck...

Integrated Buck-Buck-Boost AC/DC Converter

Single-Stage transformerless AC/DC converter received much attention in the universal line application. Unlike the existing converters a new high step-down transformerless single-stage single-switch AC/DC converter is proposed. The topology integrates a buck-buck-boost converter with low intermediate bus and output voltage. The converter utilizes a buck converter as a PFC cell and buck-boost co...

Modelling of Buck DC-DC Converter Using Simulink

In this paper, a mathematical model of a Buck Converter for simulation using Simulink without any Sim Power System Elements is illustrated. We also explain how to use Matlab’s Tuning tools to obtain better rise time, settling time and peak overshoot.
