Solar Cell Regulated Circuit

Solar Cell Regulated CircuitSolar Cell Regulated Circuit

Electronics : A solar corpuscle or photovoltaic corpuscle is a accessory that converts ablaze activity into electrical energy. Sometimes the appellation solar corpuscle is aloof for accessories advised accurately to abduction activity from sunlight, while the appellation photovoltaic corpuscle is acclimated back the ablaze antecedent is unspecified.

A solar cell, fabricated from a monocrystalline silicon wafer

Feature of This Solar Corpuscle Regulated :

Voltage Regulator

Automatic Charger

Disply Voltage & Current on LCD

LM317 Regulator Power Supply

LM317 Regulator Power Supply
LM317 Regulator Power Supply

LM317 regulator is a versatile and highly efficient 1.2-37V voltage can provide up to 1.5 Amps. of current with a large heat sink.
It is ideal for almost any application. This was my first power source workbench and I still use it.
Since LM317 is protected against short circuit, fuse is not necessary. With the decline automatic temperature control, will be shut down if overheating. However, a very powerful (and cheap!) Package contrary.

The LM317, even if it is able to supply up to 37V, the circuit shown here is limited to 25V for safety and simplicity. Any output voltage requires additional components and a heat sink more.

Oh! Sure that the input voltage was at least a couple of times as the desired output. It’s agree to use a trimmer if you’re building a fixed power supply voltage.

Issue:

Follow all safety precautions when working with mains voltage. Insulate all connections on the transformer.

Possible applications:

The desktop power variable, fixed line voltage almost all possible applications, when more than 1.5 is required.

LM338 Power Supply Regulator 13.8V 5A

LM338 Power Supply Regulator 13.8V 5A
LM338 Power Supply Regulator 13.8V 5A Scheme


Many times we needed one relatively powerful supply in order to we supply various appliances with + 13.8V, as transceivers CB, charge lead-acid batteries, etc. The circuit it uses known completed that is capable gives in the his exit, current in continuous operation 5A and 12A peak current. It does not only need few external component. Exist a point which it will be supposed you are careful in the drawing and in board. Board has been drawn so as to exist the possibility of using also two case types completing. In the first case the IC1 in case TO-220 is placed above in pcb, in second with case TO-3, it can it?s placed above in heatsink and terminal his they are connected in the connector G3, in this case, certain we leave empty the place of IC1 above in pcb.

A other point is the refrigeration of rectifier B1. If it?s placed above in pcb, then it will be supposed clinch on his piece aluminium in form U, in opposite case, if the rectifier B1 is placed except pcb should clinch in a point in his chassis and terminal are connected with suitable cross-section cables in the corresponding points above in pcb. The regulation of voltage in + 13.8V become with the trimmer TR1, (multiturn). The IC1 should in every case be placed on one suitable heatsink, which good is supportable by one fan. All the connections by the circuit become with big cross-section cables , beacause the current that passes from in them is enough high. If they are not used the connectors that appear in pcb, then you can place pins or solderer the cables at straight line above in pcb
