Hello list !!! Please excuse my interruption. I´m developing a corona discarge generator for plastic film treatment and i´m using a circuit that is quite similar to a SSTC In my case a half bridge inverter driving a ferrite core transformer with 20 turn in the primary and 800 turns in the secondary. Caracteristics of the generator: 220 VAC mains, 320 VDC bus, 30 Khz, 500V 20A pair of mosfet, 1Kw power Here some short videos of the aplications: https://www.youtube.com/watch?v=zoL1kc9MtPQ https://www.youtube.com/watch?v=Cv-UxYltXxo https://www.youtube.com/watch?v=VCjmMHeI9Ug https://www.youtube.com/watch?v=StgbV766dqQ Due to its resonant behaviour the current on the primary is cuasi sinusoidal I need to implement an over current protection on the primary to portect the bridge. Some tesla coilers use a current transformer but i can´t find a comparator or an appropriate circuit to manage the signal of the CT Has anyone any idea for this?
