Supercapacitor Based Adjustable High Power Pulse Generator for Medical Research Applications

High power pulse generators with variable parameters are helpful in many applications in the industrial and medical fields. The traditional approach to design these pulse generators is to start with a high voltage DC power supply, energy storage capacitor, and a wave shaping circuit. However, building a high-voltage DC power supply itself is a complex task and it ends up in a complicated circuit with several high-voltage components hence adding to the total cost. This paper presents a unique new approach to designing a supercapacitor-based high-voltage pulse generator with a lower number of components and simple two-winding transformer. First experimental circuit developed based on this new approach is presented here with variable pulse generator capable of several hundred volts peak voltage with loop current capability of several hundred amperes.
