Abstract
1294602 Automatic phase control CANADIAN GENERAL ELECTRIC CO Ltd 6 March 1970 [11 Aug 1969] 10846/70 Heading H3A A power supply arrangement comprises a rectifier 11 and a D.C. to A.C. inverter 16 connected between input and output terminals 10, 18, a synchronizing circuit 21 connected to the input, output terminals for producing an error signal dependent on the phase difference between voltages present at 10, 18 and control arrangement 20 for altering the inverter frequency in response to the error signal in a sense to reduce the phase difference. Signals derived from the input voltages and present at the secondary of transformer 39 are alternately gated via bidirectional switches 31-34 to a filter circuit 43, 44 by square wave gating signals derived from the output terminals and present at the secondary coils 29, 30. The output of the filter is a positive or negative voltage depending on the magnitude and sense of the phase difference. In the event of power failure, i.e. absence of signals at 10, a back-up battery 14 is automatically connected to the inverter 16 for maintaining the output voltages at 18. In case of faulty operation of the inverter, the input and output terminals are automatically interconnected by by-pass contactors 23.
