Abstract

1,059,082. Inverting; frequency changing. WESTINGHOUSE BRAKE & SIGNAL CO. Ltd. Feb. 25, 1965 [March 23, 1964]. No. 12076/64. Addition to 1,047,681. Heading H2F. [Also in Division H3] In an arrangement as claimed in claim 1 of the parent Specification which arrangement comprises a capacitor (C1) charged through a first switching means (CR1) and discharged by a second switching means (e.g. a saturable inductor) to give a burst of energy to a resonant output circuit (C2L2) so as to provide a continuous wave output, the frequency of the bursts being lower than the output frequency, means are provided to ensure that the bursts of energy are properly timed with respect to the output frequency. As shown, a capacitor C1 is charged through a rectifier CR1 and discharged into a resonant circuit C2L2 through a second switching means which consists of a pair of parallel saturable reactors SR1, SR2. A second rectifier CR11 is also provided so that the capacitor C1 may next be charged negatively, this charge also being passed to the turned circuit through the switching means SR1 and SR2, and the rectifiers CR1, CR11 operate alternatively. Control windings W1 . . . W4 are provided on the saturable reactors, which are controlled to determine the instants at which these conduct, and hence the required phase relationship. The voltage across C1 is applied to a transformer T1 and hence to transistors VT1, VT2 which conduct alternatively. The output of these transistors are applied to transistors VT3, VT4 which constitute a bi-stable circuit, and the outputs of these are applied, via additional apparatus not shown, to trigger the rectifiers CR1, CR11, so constituting an oscillator arrangement. The voltage across the output circuit C2L2 is applied to a transformer T2 controlling a transistor VT8, and provides a negative pulse every cycle at the voltage zero of the highfrequenoy output across a resistor 14. When V1 is non-conducting these pulses are suppressed by a circuit comprising D13, RV, Zener diode ZD1 and transistor VT10. When, however, V1 conducts the next negative pulse switches transistor VT9 into conduction, and a rectifier CR5 is thereby triggered into conduction. A forward bias is thus applied to a rectifier CR6 via transistor VT5. Now when the saturable reactor SR1 or SR2 switches, an output is derived.via W3, W4, to render transistor VT11 conducting and hence trigger CR6. Thus there is produced across the rectifier CR6 a pulse starting at the cross-over instant of the output voltage and ending at the conduction instant of the saturable reactor switching means. The duration of this pulse is therefore a measure of the undesired phase difference aforementioned. These pulses are smoothed, and applied to an amplifier VT6, VT7, which feeds a drives: B1 controlling a bridge B2 whose output feeds the windings W1, W2 controlling the saturable reactor so as to reduce this phase difference. In a further circuit (Fig. 4, not shown), the second switching means comprises an uncontrolled saturable reactor in parallel with a controlled rectifier. Simpler control circuitry is required for this embodiment.
