① Explain the mechanism of power supply in this experiment.
Electric power supply company provide us AC voltage. But almost electric circuit need to use DC voltage. Power supply is a system of transforming AD voltage to DC voltage. This is almost same as express the 5V PC static voltage source. Capacitor takes a role of making static voltage at the sine form AC voltage. In other words, It fills up a valley of voltage. If there is Rl, It has also a little riffles. And LH340T5 takes a rlos of voltage regulator and reduces a voltage and riffles.
- Transformer : Increase of decrease the AC voltage.
- Rectifier : Trasform AC input voltage to DC output voltage.
- Filter : Reduce the riffles. Make a flat DV voltage.
- Bleeder resister : It helps capacitor to recharge or discharge and improve a voltage changing rate.
- Regulator : Supplies a demanded regular voltage and current.
② Understand the elements used in each step, then analyze circuit
with respect to following instructions.
1) Characteristics of transformer
A transformer is a device that transfers electrical energy from one circuit to another through inductively coupled conductors — the transformer`s coils or "windings". Except for air-core transformers
