Abstract
The invention concerns a high power power supply with output power in excess of 5 kilowatts, by way of example, for the supply of electromagnets in the area of electromedicine and nuclear physics. In order to regulate the output current, power thyristors 28 are utilized within the two bridge rectifier circuits 2 and 3, operated with phase control regulation. In order to keep the output current constant, two transistor final control elements 10 and 11 regulated by a control-gain amplifier are used. Two charging capacitors 6 and 7 are provided for energy storage, the capacity of which is sufficiently large that the commutation of the power thyristors 28 transpires by means of self-extinguishing in a currentless state, whereby conducted as well as irradiated electrical interferences are eliminated.
