E-rickshaws, as emerging transport modes, notably affect mixed traffic flow on urban roadways. To evaluate their influence relative to other vehicle types, this study aim was to determine the Passenger Car Unit (PCU) value for e-rickshaws, as the Indian Roads Congress has yet to assign one. Three analytical methods were used: Chandra's method, the homogeneous coefficient method, and multiple linear regression. Data were gathered via three-hour video recordings at three different locations, each in Hapur and Sonipat. Using VLC media player, vehicle speeds and counts were extracted for analysis. The data were then processed in SPSS and Excel to derive...

The performances of different driving circuits configurations designed for silicon carbide MOSFET transistors are compared in this research. The simulation of the double-pulse test (DPT) was performed with the use of three driving circuit configurations. The SiC MOSFET NTH4L022N120M3S has great dynamic parameters, which made it suitable for the DPT simulation. It was performed with six different driving voltage ranges, all within the range between -10 V and 20 V. The results were taken across the wide range of driving resistances placed between the driver and the SiC MOSFET, where the switching losses were taken. Drawing from the observed measurements...
