Design Strategy for a 3-Phase Variable Frequency Drive (VFD) (Electrical Project)

This paper describes the design processes for a 3-Phase Variable Frequency Drive (VFD) as broken up into two stages: The AC-DC converter and the DC-AC converter. It acknowledges three (3) design versions, all. The output of the Continue reading

Tradeoff Analysis and Joint Optimization of Link-Layer Energy Efficiency and Effective Capacity Toward Green Communications (Electronics Project)

A joint optimization problem of link-layer energy efficiency (EE) and effective capacity (EC) in a Nakagami-m fading channel under a delay-outage probability constraint and Continue reading

Article Dynamical Model of Harmonic Generation in Centrosymmetric Semiconductors at Visible and UV Wavelengths (Electrical Project)

We study second and third harmonic generation in centrosymmetric semiconductors at visible and UV wavelengths in bulk and cavity environments. Second harmonic generation is due to a combination of Continue reading

Sensorless Rotor Position Estimation For Brushless DC Motors (Electrical Project)

Brushless DC motor speed is controlled by synchronizing the stator coil current with rotor position in order to acquire an accurate alignment of stator rotating field with rotor permanent-magnet field for efficient transfer of energy. In order to accomplish this Continue reading

AC Power Monitoring System (Electrical Project)


Motivated by high energy costs, people and organizations want to cut back on their energy consumption. However, the only feedback consumers typically receive is a monthly bill listing their total electricity usage (in kWh). Some companies have Continue reading
