Abstract

950,186. Inverting. WESTINGHOUSE BRAKE & SIGNAL CO. Ltd. Jan. 5, 1961 [Jan. 5, 1960], No. 306/60. Heading H2F. [Also in Division H3] An inverter comprises two switching devices for connecting a transformer in alternating polarity to a D.C. supply, and a capacitor connected to the control terminals of the switching devices via a breakdown device and arranged to be charged from a secondary winding of the transformer, whereby when the device breaks down the polarity of the said connection to the supply is reversed. The Figure shows a transistor push-pull inverter of the type having regenerative feedback from collector windings 2, 3 to base windings 4 and 5 and feeding a load 8. A further winding 6 charges a condenser 20 through a resistor 19 until the voltage across the condenser is sufficient to cause a breakdown device 26 to change from its high conducting condition to a low conducting condition. This causes the condenser to apply to the bases a voltage such that the conductivity conditions of the two transistors reverses. The condenser discharges causing the device 26 to become highly non-conductive again and the condenser then charges in the opposite direction until break down again occurs and causes a further reversal of the conducting condition. The diode bridge 22, 23, 24, 25 permits the device 26 to be operative in one direction only but may be omitted, in which case, if device 26 is asymmetrical, the output waveform will be asymmetrical. Two devices connected back-to-back may also be used. As a further alternative, a three electrode breakdown device may be used, control of the frequency of operation being effected by a current supplied to the third electrode or by synchronizing pulses applied to the electrode. To minimize variation of frequency with supply voltage changes the voltage output of the winding 6 may be stabilized by a Zener diode circuit. Initiation of oscillation on switching on may be ensured by connecting a resistance between a negative supply terminal and the base of one transistor.
