This paper presents a Pulse Width Modulation (PWM) based method for Active Power (AP) and Reactive Power (RP) measurements in electric sinusoidal and Non-sinusoidal power systems. The method takes advantage of the fact that frequencies present in a power line are of a specific fundamental frequency range (a range centred around the 50Hz or 60Hz) and ...

Research for PWM rectifier based on voltage space-vector Pulse-Width Modulation
2007 International Conference on Electrical Machines and Systems (ICEMS), 2007Based on the operating principle of PWM (pulse-width modulation) rectifier, aiming at the major factors which influence the power factor of rectifier, switching frequency and its losses, an improved traditional method of SVPWM (space-vector pulse-width modulation) has been proposed by applying the SVPWM technology.

Position Control of Hydraulic Actuators Using Fuzzy Pulse Width Modulation (PWM)
Applied Mechanics and Materials, 2015Hydraulic actuators are widely employed for industrial automation for its high power over weight ratio, functionality in tough operating conditions and low cost. However, the dynamics of hydraulic systems are non-linear and the system subjected to non-smooth and discontinuous non-linearities due to directional change of valve opening, friction, valve ...

Control of the speed of a DC motor by employeeing pulse width modulation (PWM) technique
2009 12th International Conference on Computers and Information Technology, 2009This paper is mainly focused on the technique of pulse width modulation for controlling the speed of a 12 volt DC motor more efficiently. A potentiometer was used to generate a wide variety of pulses. The output of the controlling circuit (Pulse Width) was connected to the second circuit as input for direction control.

Energy Regenerative Damper Using Pulse Width Modulated (PWM) Step-up Chopper
Volume 6: International Symposium on Motion and Vibration Control, 1999Abstract This paper describes a new technique of improving the efficiency of an energy regenerative damper. It is intended for an electro-dynamic type vibration damper to regenerate vibration energy efficiently. Normally regenerative damper can regenerate vibration energy only at high speed motion.
