Four Channel 6.5 kV, 65 A, 100 ns–100 µs Generator with Advanced Control of Pulse and Burst Protocols for Biomedical and Biotechnological Applications

Pulsed electric fields in the sub-microsecond range are being increasingly used biomedical and biotechnology applications, where demand for high-voltage high-frequency pulse generators with enhanced performance flexibility is pushing limits of power solid state technology. In scope this article, a new pulsed generator, which includes four independent MOSFET based Marx modulators, operating individually or combined, controlled from computer user interface, described. The generator capable applying different shapes, unipolar to bipolar pulses into biological loads, symmetric asymmetric modes, voltages up 6.5 kV currents 65 A, widths 100 ns µs, including short-circuit protection, current voltage monitoring. This scientific tool can open research possibility due it provides generation, particularly adjusting width, polarity, amplitude pulse-to-pulse. It also permits burst mode 5 MHz channels, example application synchronized pulses, shown together other characteristics generator.
