Optimal Time-Domain Sinusoidal Pulse Width Modulation Technique
Siddharth Tyagi, Isaak Mayergoyz
An optimal time-domain pulse width modulation technique is presented for single-phase and three-phase inverters under the constraint of sinusoidally modulated voltage pulse widths.…
Time-Domain Analysis of PWM Inverters
Siddharth Tyagi, Isaak Mayergoyz
The time-domain analysis of pulse width modulated (PWM) single-phase inverters is presented for different load circuits. It is demonstrated that this analysis can be reduced to the…
Experimental detection of surface spin-polarized electron accumulation in topological insulators using scanning tunneling microscopy
S. Tyagi, M. Dreyer, D. Bowen +6
Spin-momentum locking in the surface mode of topological insulators (TI) leads to the surface accumulation of spin-polarized electrons caused by bias current flows through TI sampl…
Study Of Surface Spin-Polarized Electron Accumulation In Topological Insulators Using Scanning Tunneling Microscopy
S. Tyagi, M. Dreyer, D. Bowen +6
The results of scanning tunneling microscopy experiments using iron-coated tungsten tips and current-carrying bismuth selenide () samples are reported. Asymmetry in tunne…
Optimal Time-Domain Pulse Width Modulation for Three-Phase Inverters
Siddharth Tyagi, Isaak Mayergoyz
A novel optimal time-domain technique for pulse-width modulation (PWM) in three-phase inverters is presented. This technique is based on the time-domain per phase analysis of three…
