Magna-Power Electronics MT Series uses the same reliable current-fed power processing technology and controls as the rest of the MagnaDC programmable power supply product line, but with larger high-power modules: individual 150 kW and 250 kW power supplies. The high-frequency IGBT-based MT Series
All MagnaDC programmable DC power supplies utilize high-frequency IGBT- and MOSFET-based power processing in a current-fed topology. This topology adds an additional stage over the conventional voltage-fed topology for enhanced control and system protection, ensuring that even under a fault condition, the power supply will self-protect.
250 kW modules come standard with an embedded 12-pulse harmonic neutralizer, ensuring low total harmonic distortion (THD). Even higher quality AC waveforms are available with an external additional 500 kW 24-pulse or 1000 kW 48-pulse harmonic neutralizers, designed and manufactured exclusively by Magna-Power for its MT Series products.
IEEE has introduced standard, IEEE 519, which defines recommended limits. Implementing this standard requires a knowledge of the power system and other loads producing harmonics. Unfortunately, the standard can allow the same power supply to possibly exceed limits in one application and not in another.
