Abstract
A resonant circuit successively assumes charging and discharging conditions which form the primary circuit of a transformer in a power pack constructed according to the principle of a resonant converter, and a switch-over pulse is generated after each initiation of the charging condition and depending on the existancee of current and/or voltage values for resonance in the resonant circuit, and the switch-over pulse ends the charging condition by using a switching means and initiates the discharging condition so as to produce an improved resonant converter.
