Abstract
1421195 Automatic control of micro-wave generation SIEMENS-ALBIS AG 31 Jan 1973 [25 Feb 1972] 4977/73 Heading G3R [Also in Division H3] In a circuit for pulsing a micro-wave transmitter 9, the pulse modulator 10 for the transmitter obtains its high voltage supply from a transformerless rectifier 1 and a D.C. to D.C. converter 4 and the pulse power is maintained constant by deriving a control signal at 8 dependant upon the current supply and which controls the mush-space ratio of the output of the rectifier via a photocoupler 3 at the frequency of the pulses. As shown the current is monitored via a transformer 12 and the mush-space controller comprises components 2, 5, 6,7.
