Abstract
A power supply for predominantly inductive loads includes at least two controllable voltage sources, each of which has a voltage-setting unit connected at its input side to a d.c. voltage source, and which delivers a controlled output voltage at its output terminals. The d.c. voltage sources respectively connected to the voltage-setting units are separated in potential, and the output terminals of the voltage-setting units are connected in series. A first of the controllable voltage sources is fashioned for basic load operation for supplying a basic output voltage, and at least a second of the controllable voltage sources is fashioned for peak load operation for supplying peak output voltages which exceed the basic output voltage.
