Abstract

1,020,898. Rectifying. LICENTIA PATENTVERWALTUNGS-G.m.b.H. Nov. 14, 1962 [Nov. 15, 1961], No. 43062/62. Heading H2F. A rectifying circuit supplying current to a load 6 in one direction or the other through rectifiers 2, 3 or 4, 5 from a tapped transformer 1 has means to detect the instant when both rectifiers have stopped conducting, so that a rapid current reversal may be obtained without a large circulating current occurring at the change over. When rectifiers 2 and 4, for example, are not conducting, then the voltage across them exceeds the threshold voltage of the pair of Zener diodes 8. If this voltage is positive, then diode 11 conducts and transistor 14 is switched off, having been biased on previously by resistor 13. If the voltage is negative then diode 10 conducts, transistor 12 is switched on, and, as before, transistor 14 is switched off.
