Speed increasing scheme by using 3000v dc power supply for low-speed Maglev

Variable supply-voltage scheme for low-power high-speed CMOS digital design

This paper describes a variable supply-voltage (VS) scheme. From an external supply, the VS scheme automatically generates minimum internal supply voltages by feedback control of a buck converter, a speed detector, and a timing controller so that they meet the demand on its operation frequency. A 32-b RISC core processor is developed in a 0.4m CMOS technology which optimally controls the intern...

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 ...
