Abstract

A flyback EHT and sawtooth current generator for television display apparatus including a transformer and switching means connected thereto which are conducting during a scan period and are non-conducting during a flyback period, and reactances whether parasitic or nuts connected to the transformer which together with the transformer constitute a network having a minimum of three prescribed resonant frequencies during the flyback so that a scan which is substantially without any oscillations and a flyback EHT pulse having a wide and flat peak is produced.
