Pulse width reduction due to RF filtering in synchronized time-lens source

Synchronized time-lens source for coherent Raman scattering microscopy

Synchronized time-lens source is a promising source solution for coherent Raman scattering (CRS) microscopy. Contrary to conventional (single) time-lens source which is driven by electrical signals from a fixed-frequency radio-frequency (RF) source, the synchronized time-lens source is driven by electrical signals from optoelectronic detection of the optical output of the mode-locked laser to w...

Glissadic overshoots are due to pulse width errors.

Glissades are the slow, gliding eye movements often appended to the end of human saccadic eye movements. They have been used as an aid in diagnosing disease states, eg, multiple sclerosis and vascular lesions. Glissades are a consequence of a mismatch between the sizes of the pulse and step components of the pulse-step motoneuronal controller signals. This physiological and simulation study sho...

Torque Ripple Reduction in Switched Reluctance Motors by Rotor Poles Shape and Excitation Pulse Width Modification

In this paper, at first, a 24/16 three-phase switched reluctance motor is designed, then the rotor poles shape tips corrected for reduction ripple of single-phase torque waveform. By doing this, the single-phase torque waveform has a flat surface and consequently, the single-phase torque ripple is reduced. Also, due to the commutation between the machine phases, the torque drops during this tim...

Pulse Width Modulator for Voltage Regulation in Voltage Source Inverter

Pulse Width Modulated (PWM) voltage source inverters (VSIs) are extensively used in industrial and domestic applications. The versatile natural sampled sinusoidal PWM (SPWM) method can perform output voltage control with acceptable indices. In these PWM-VSI, the coarse voltage regulation is done with change in modulation depth while fine voltage regulations have not been addressed by other auth...
