Two power supply for MGDP-2,5 electromagnetic melt sterrers, mixers 2A and 2B

For the first time, a power supply source of the classical design with a DC link and an inverter with IGBT transistors was used for MGDP-2,5 electromagnetic stirrers. As a result, it was possible to eliminate switching overvoltage, increase the mixing capacity and ensure high reliability of the power part.
