Medium-Voltage Drives (MVD) - Pulse Width Modulation (PWM) Techniques
2023 Second International Conference on Electronics and Renewable Systems (ICEARS), 2023In order to keep up with rising customer demand, more and more MVDs are being used to fuel MV motors. Power delivery to a load may be modulated by changing the pulse width. A digital signal might be transformed into an analog one using the pulse width modulation (PWM) technique.

A New Switching Strategy for Pulse Width Modulation (PWM) Power Converters
IEEE Transactions on Industrial Electronics, 2007This paper presents a new switching strategy for pulse width modulation (PWM) power converters. Since the proposed strategy uses independent on/off switching action of the upper or lower arm according to the polarity of the current, the dead time is not needed except instant of current polarity change.

Computers and Electronics in Agriculture, 2021
Abstract Pulse width modulation (PWM) is currently implemented in agricultural sprayers to deliver the expected flowrate by managing the duty cycle and maintaining the target pressure and provide the desired droplet size. However, there are still issues about the application errors caused by the pressure variations when using this system as it may ...

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.
