Sinusoidal Asymmetric PWM modulation based three phase inverter 1.0 Description
Description: The model simulates asymmetric modulation which can be observed at second scope by zooming the waveform on time axis. In this modulation technique the reference signal is sampled at positive as well as at negative peak of the carrier and held constant between two sampled points. Three phase inverter was used to demonstrate the effect of asymmetric modulation on the output and Fourier analysis is presented using GUI block.
The model simulates three phase inverter with symmetric PWM modulation in which reference is sampled at the positive peak of the carrier and is held constant till the next positive peak of the carrier appears. The model demonstrates symmetric...
The model simulates space vector based three phase inverter with the state space model of thefilter. The model parameters such as frequency, switching frequency, load parameters, voltage, modulation index and filter A,B,C,D parameters.
This model simulates three phase inverter. Sawtooth waveform has been used as the carrier. Triplen of level 1/6 of reference were injected in the reference to utilize the maximum DC link voltage. The output voltage range increases by injecting the...
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
