Abstract

The invention relates to a power supply unit which includes an inverter having output connections whereto the primary winding of a transformer is connected via a series capacitor. The rectified secondary voltage of this transformer is applied to a use which requires a high short-time power in a first mode of operation and a lower continuous power in a second mode of operation. The maximum permissible continuous power can be increased by means of an auxiliary inductance Lh which is active in the second mode of operation but inactive in the first mode of operation.
