SAN MIG 200MF
§2.3 Working Principle
The working principle of SANMIG 200MF is shown as the following figure. Single phases
work frequency AC 220V (50 Hz) is rectified into DC (about 380V), then is converted to medium
frequency AC (about 44KHz) by inverter device (IGBT), after reducing voltage by medium transformer
