5. CONSTRUCTION AND OPERATION
The basis for the construction of the power conversion electronics welders are made in MOSFET technology enables operation at frequencies above
100 kHz.
The principle consists of a single-phase rectified voltage to the power supply voltage, conversion of the resulting DC voltage to a square
wave high frequency voltage transformation in the range required by the welding process and re-erection of the resulting voltage on the DC voltage.
