Abstract – The current source converter represents the dual counter part to the better known and more frequently used voltage source converter. As such due to duality rules many offthe-shelf solutions concerning the VSC can be used in a modified manner to handle the CSC. This work gives a comprehensive overview of CSC PWM methods and shows how they are to be distinguished. Then based on duality...

Torque ripple is a defect of switched reluctant motors. DITC (direct instantaneous torque control) harnessed to solve the problem as traditional method, which superior TSF (torque sharing function). In this paper, new controller proposed with modified hysteresis and PWM in DITC. With algorithm, error will be reduced The algorithm effective improve sample 0 status period. based on application ze...

in this study, a new adaptive controller is proposed for position control of pneumatic systems. difficulties associated with the mathematical model of the system in addition to the instability caused by pulse width modulation (pwm) in the learning-based controllers using gradient descent, motivate the development of a new approach for pwm pneumatics. in this study, two modified feedback error l...

Aimed at the pulse width modulation (PWM) voltage noise and power imbalance in three-phase cascaded H-Bridge (CHB) inverters, a modified random PWM (RPWM) strategy, named power-balanced RPWM (PB-RPWM) is proposed this paper. The PB-RPWM strategy mainly includes three steps: (1) signals are generated by compared wave with level-shifted carriers; (2) circularly distributed between CHB units logic...

Private Webmail 2.0 (Pwm 2.0) improves upon the current state of the art by increasing the usability and practical security of secure email for ordinary users. More users are able to send and receive encrypted emails without mistakenly revealing sensitive information. In this paper we describe user interface traits that positively affect the usability and security of Pwm 2.0: (1) an artificial ...
