Sinosoidal PWM based three phase inverter -- Sawtooth carrier -- Triplen injected in the reference 1.0 Description
Description: 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 triplen harmonics in the reference provided that two peaks of the new reference are equal to the peak of the fundamental of reference.
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.
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...
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 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...
