Circuit Diagram On-off control SCR with logic gate IC

Robotronicdiagram. - Here is Circuit Diagram On-off control SCR with logic gate IC like in Figure 1 below. The main component in this DC to DC converter is MC34063 IC. With this circuit schematic we can charge easily our microcontroller using 3.7V battery. In here we will show you also the component part ans simple description of this circuit diagram. 

Circuit Diagram 

Component Part
  1. IC 1 CD40106
  2. IC2 CD4066
  3. Capacitors
  4. Resistors
  5. LED
  6. Q1 2N3604
  7. Diode
  8. SCR

Circuit diagram like in Figure 1 above is Circuit Diagram On-off control SCR with logic gate IC. According Eleccircuit site describe that this is an SCR control circuit with digital logic. The behavior of the circuit. The input A to control current for SCR turn ON.The input B will stop the current SCR (OFF). Set the two input signals to a logic “1” to control, and it asked them to different times.

      The control SCR to conductors. When input A is logic “1” IC1a will return to a logic “0”. The C1 is charged from a positive light, through R3, The IC1b to the logic “1”, the output pin. This is a mono-Stable, a pulse of logic “1”, the value of C1, R3, Through the diode D1.The only positive voltages. The trigger pin through the gate of SCR.The R5 limits current to the gate too.

      When the SCR is triggered, it will conductors (ON) and hold. The trigger voltage is changed. The positive voltage drop R6, pass catode and anode pin of the SCR are the voltage across R7. Which is greater than the voltage drop across R6. Because the resistance of R7 is over. It makes the Q1 bias, making driving LED1 light flow.
