Transistorized blocking oscillator with bridge rc time setting circuits
Abstract
Abstract A BLOCKING OSCILLATOR IS PROVIDED WITH A TRANSFORMER HAVING A PRIMARY AND SECONDARY WINDING, A TRANSISTOR HAVING A BASE, EMITTER AND COLLECTOR, A FREQUENCY-DEPENDENT BRIDGE HAVING A FIRST AND A SECOND BRANCH, AND FIRST AND SECOND DIODES. THE FIRST BRANCH INCLUDES A CAPACITOR AND A RESISTOR, AND THE SECOND BRANCH INCLUDES TWO RESISTORS. THE PRIMARY WINDING OF THE TRANSFORMER IS CONNECTED TO THE BASE AND EMITTER OF THE TRANSISTOR. THE SECONDARY WINDING OF THE TRANSFORMER IS CONNECTED AT ONE END TO THE COLLECTOR OF THE TRANSISTOR, THE FIRST DIODE AND THE FIRST BRANCH OF THE FREQUENCY-DEPENDENT BRIDGE, AND IS CONNECTED AT ITS OTHER END OF THE COLLECTOR OF THE TRANSISTOR, THE SECOND DIODE AND THE SECOND BRANCH OF THE FREQUENCYDEPENDENT BRIDGE. A POWER SOURCE IS ALSO COUPLED WITH THE SECOND BRANCH.
