The main advantage of the IGBT Rectifier is the fact it produces a sinusoidal input current with low harmonics at the input with unity Power Factor through most of the load range. The 4 quadrant operation is also an important plus due to its versatility and better response.
In conclusion:
IGBT rectifiers have “cleaner” input currents, which translates into better performance with a small cost in efficiency. In general, they have less ripple factor and better harmonics performance. They easily comply with all the Grid Harmonic Injection regulations, in fact exceeding all the requirements. IGBTs work under more recent technology.
Overall, I could say they are more cost-efficient long-term.
At Sinepower, we use IGBT technology in our SFC and in our V2G chargers, while most of the competition out there still opt for the older 6 and 12 pulse rectifiers.
