Abstract :
Development of FPGAs (field programmable gate array) allows those to be used as modern control platforms for power electronics. The increase of the computational power makes it possible to implement a whole control system inside one chip. Massive parallel computing resources can be utilized in digital control of power electronics. In this paper a switch-mode welding machine control is presented. A control consisting of both analog and digital parts is replaced with a new digital control implemented in a Spartan-3 FPGA device. As a result step response behaviour is presented with both controls and with fully digital control overshoot is removed almost completely
