Abstract
M.Ing. (Electrical And Electronic Engineering)
An AC/DC force commutated controlled converter, designed for use
in a pulsed laser power supply, is presented here. The converter is
controlled with a digital signal processor (DSP). The converter has
to supply a stable DC voltage to the load, while drawing sinusoidal
currents at unity power factor from the supply grid.
The design of such a converter is discussed here, as well as the
experimental evaluation of a prototype converter able to supply
30kW to a load.
