Let’s first remove V1. R1 cannot be left unconnected, because in the initial circuit there was current flowing through it. Therefore, let’s ground R1 (see Figure 2). Figure 2 We can see that our amplifier becomes an inverter, which has its non-inverting input connected to ground throug...
METHOD AND DEVICE FOR OVERCURRENT DETECTION OF ELECTROSTATIC INDUCTION TYPE SELF-ARCEXTINGUISHING ELEMENT, AND DERIVE CIRCUIT AND INVERTER EMPLOYING SAMEPURPOSE:To detect overcurrent due to short circuits of arm and the like by judging overcurrent if the base voltage of a self-arcextinguishing ...
As the output voltage continues toincrease under the action of flyback,Q1is driven even harder, causing its collectorvoltage to fall. Since the collectoris connected to the control input of the555 timer that is nominally the upperlimit above (2VCC/3), this causes thecapacitor to charge and ...
