Abstract:
PCT No. PCT/DE96/00849 Sec. 371 Date Apr. 23, 1997 Sec. 102(e) Date Apr. 23, 1997 PCT Filed May 14, 1996 PCT Pub. No. WO97/11529 PCT Pub. Date Mar. 27, 1997A circuit arrangement for multiple use of a transformer core, comprising a winding with center tap on the primary side and two separate windings on the secondary side, has a controlled switch in each feed line for the two primary windings which is preferably clocked with high frequency. A rectifier is connected to the first secondary winding in particular for forming a switching power supply, which is thus supplied with energy. An FET transistor is coupled to the second secondary winding, in particular for forming a driving pulse transmission, preferably via two Z-diodes with anti-serial connection, which transistor is thus supplied with driving pulses. The magnetic circuit for the transformer is actuated via switches which change polarities on the primary side of the transformer. The switch-on pulse duty factor for the switches is selected to be higher than 50%.
