Abstract

An apparatus for charging living tissue with electrical pulses has a charging capacitor that, for discharging, is connected via a controllable switch to electrodes in the region of the tissue. In order to achieve a curve of the current through the electrodes that deviates from an exponentially decaying curve, the switch is switched on and off with a varying switching frequency while the tissue is being charged with pulses and the current supplied to the tissue is smoothed by circuit components.
