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.

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.

Simulation of pulse width modulated (PWM) chopper drives using z-transformation
MELECON '98. 9th Mediterranean Electrotechnical Conference. Proceedings (Cat. No.98CH36056), 2002In this paper, a class-C chopper circuit is modeled using z-transformation including the time variation of the pulsewidth modulated (PWM) signal. A closed-loop speed control system using a direct current (DC) motor fed by the chopper is then simulated.

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.
