Experimental High-voltage AC Generators for Cardiological Purposes

This paper is focused on a development of high-voltage AC generators, which are proposed for experimental use at cardiology, especially for treatment of arrhythmia. Both generators work as DC-AC inverters with step-up pulse transformer, which provides a galvanic isolation of a load from other circuits. An older generator is designed for high-frequency electroporation, while a new generator works at lower frequency, which seems more advantageous for the arrhythmia treatment. A modular arrangement of the new generator allows to create a multi-channel device or an asymmetrical waveform generator. The whole device is controlled by a main processor board, which also provides some measurements. Set and measured quantities are shown on a display.
