Three Phase Induction Motor

SPWM technique for Three Phase Inverter. Analysis fundamental improvement with respect to modulation index variation is done in simulation. Analysis can be done also for switching frequency variation for shifting the dominant harmonics

The model simulates the three phase inverter with space vector pulse width modulation. The SVPWM idea has been used from the Matlab drive library.

This demo illustrates use of both SimPowerSystems and Simscape to model a On-Load Tap Changing (OLTC) 120/25 kV transformer regulating voltage on a three-phase 25-kV distribution network.The demo is similar to the power_OLTCregtransformer demo of SimPowerSystems. However, instead of using...

This demonstration illustrates the use of a complex space vector to represent a three-phase signal . It also shows the transformation of the 3-phase signal 'ABC' into an equivalent 2-phase system 'alpha_beta'. The only restriction to the 3-phase signal is that the zero-sequence component is zero...
