We describe the design and construction of a high voltage, variable frequency power supply for driving plasmas and testing the frequency responses of Dielectric Barrier Discharges (DBDs). DBDs are frequently used for surface treating, ozone production, and as UV sources. However, before these can be studied, a high voltage DBD driver must be designed and implemented. Much strife may be had in designing such a driver with a respectable bandwidth when the available transistors can only handle a fraction of the desired output voltage. Recently, however, MOSFETs have been made available which can switch several thousand volts. This makes our goal easier to implement. We present our work on developing this power supply.
