GaN-based versatile waveform generator for biomedical applications of electroporation

Abstract

Biomedical applications often require high-performance power supplies for diagnosis and treatment systems. In particular, modern electroporation techniques for cancer treatment require high-voltage generators with versatile waveform generation. In this context, sinusoidal waveform generation has been recently identified as beneficial for electrochemotherapy cancer treatments. This paper proposes the design of a high-voltage high-frequency arbitrary waveform generator taking advantage of Gallium Nitride (GaN) devices. The proposed converter has been designed and implemented, achieving a 1-MHz 2000-V output voltage. It has been electrically tested and applied to electrochemotherapy treatments in mice, demonstrating the feasibility of this proposal.
