Hi everyone, I've got an application that requires a small (400 mm^2) footprint board-mount transformer that can take a 5VDC, low-current (<1A) square-wave signal and output a 3000Vp-p, 500kHz signal in the tens of mA (5W max output power). Used for generating an abnormal glow discharge in a microcavity. Does anyone know of a particular type of transformer that would be ideal for the application? I've found some current-sensing units that may work, but I don't have a grip of the differences between the types. Efficiency is key. Thanks taking the time to read.
