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 ...

Boost Converter for Power Factor Correction of DC Motor Drive

With the increasing demand for power from the ac line and more stringent limits for power quality, power factor correction has gained great attention in recent years. A variety of circuit topologies and control methods have been developed for the PFC application. While the discontinuous conduction mode (DCM) converters such as boost and flyback converters are well suited for low power applicati...

A novel multicell DC-AC converter for applications in renewable energy systems

This paper presents a novel dc–ac converter for applications in the area of distributed energy generation systems, e.g., solar power systems, fuel-cell power systems in combination with supercapacitor or battery energy storage. The proposed converter is realized using an isolated multicell topology where the total ac output of the system is formed by series connection of several full-bridge con...

Fuzzy Remote Controller for Converter Dc Motor Drive

In this paper fuzzy speed and current controllers are proposed for closed loop speed control of a converter fed dc motor drive. The performance of the fuzzy controlled system is compared with that of P-I controlled system to establish its suitability. The controller is implemented in a 486 based PC, and attempt is made to control the motor from a remote operating point via FM transmitter and re...
