Circuit Diagram and Circuit Operation

Objective:

1. To learn and assess the circuit diagram.
2. To study the circuit operation.
3. To learn the component position before construct

Procedure:

Circuit Diagram

 

Figure: this figure shown the circuit diagram of Solar power

 

CIRCUIT OPERATION

•  POWER SUPPLY

Capacitor C1 is charge by means of the solar cell X1, which provides 6V to 12V, and 10 mA upwards-that is, a relatively small solar cell will provide adequate charge. 12V should be the maximum actual unloaded output of the solar cell in full sunlight-therefore one having a load voltage rating of 6V or 7.5V will most likely suit.The voltage from the solar cell is regulated by zener diode D1. Resistor R1 ensures that D1 and rectifier diode D2 are never overloaded. Diode D2 prevents reverse leakage of the current and it’s inclusion (with solar cell disconnected) extends the charge holding time of C1 more then ten-fold.

•   VOLTAGE REGULATION

TR2 is employed in such a way that it’s conductance is automatically adjusted to keep a constant voltage across capacitor C2 as the voltage across C1 falls. The control voltage is provided at the collector (c) of bipolar transistor TR1, which forms part of a variable potential divider, through preset VR1 and thermistors R3 and R4

Result and analysis:

1. The circuit diagram take from the magazine as the example before we do construct at the software
2.  The circuit diagram is important to understand the circuit operation before we do the simulation.
3. some study do to understand each of the component  and circuit arrangement
