Project manager – Flexible high-voltage generator

Project manager – Flexible high-voltage generator

A flexible high-voltage pulse generator in combination with a continuously operating conveyor system was necessary for the process development in selective material fragmentation.

The generator had to be adjustable independently in the following parameters: voltage, energy per pulse and inductance. That is why I designed the generator so that voltages (40kV – 200kV), capacitance (2.5nF – 75nF) and number of stages (2 – 4) could be selected via the control.

I also created and implemented a new concept for conveying the materials to be treated, a metallic conveyor belt as a counter electrode.
