Mains supply
The mains supply is realized over three fast semiconductor fuses.
Rectifier part
The rectifier consists of one three phase diode bridge, smoothing elements and one DC overcurrent limit circuit.
Converter part
The converter part consists of the oscillator capacitors, IGBT modules, MF output connection and the control. The oscillator capacitors and the oscillator transformer are mounted in the separate adaptor frame and connected with the generator by the special flexible MF cable and cooling water pipes with the maximal length of 4 m. Upon the special customer request it is possible to integrate the output part in the generator frame.
Control
The generator is completely controlled by the system Simatic S7 with touch screen. The operational panel is used for entering the working parameters and by that to control the equipment. Via the corresponding connector it is possible to operate the generator from remote devices. The important working data as well as the eventual faults will be displayed on the LCD display of the operational panel. As a special option we can offer the converter with two different working frequencies for the alternative work.
