Mobile phones generally charge with 5v regulated DC supply, so basically we are going to build a 5v regulated DC supply from 220 AC. This DC supply can be used to charge mobiles as well as the power source for digital circuits, breadboard circuits, ICs, microcontrollers etc.

## Which circuit is used in mobile charger?

Mobile phones generally charge with 5v regulated DC supply, so basically we are going to build a 5v regulated DC supply from 220 AC. This DC supply can be used to charge mobiles as well as the power source for digital circuits, breadboard circuits, ICs, microcontrollers etc.

How does a mobile charger circuit work?

A D6 diode is connected between the output of the IC and a limiting output voltage of the battery up to 6.7V is used for charging the battery. When the switch is pushed, it latches relay and starts charging the battery.

What are the components of mobile charger?

Part list of the mobile charger circuit

• Q1 – 13001 transistor.
• D1 – 1N4007 diode.
• D2 – 6.2V Zener diode.
• D3 – 1N4148 diode.
• D4 – SB260 schottky diode.
• R1 – 6.8 Ohm – 1/2 watt.
• R2 – 1 MOhm – 1/4 watt.
• R3 – 6.8 kOhm – 1/8 watt.

### Do phone chargers convert AC to DC?

A mobile charger works on the simple principle of conversion of AC (alternating current) to DC (direct current).

What is charging circuit?

A battery-charging system includes a first charging circuit connected in series with a plurality of battery cells for controlled current charging. A second charging circuit applies a controlled voltage across each individual cell for equalization of the cells to the fully charged condition.

Do phones charge with AC or DC?

That is why portable electronics – flashlights, cell phones, laptops – use DC power; they have to store it. Plug-in vehicles are portable so they use DC batteries too (although most of them have AC motors – a complicating step we may consider another day).

## What is battery charger circuit?

It is a simple method that uses a small constant current to charge the battery during the complete charging process. When the battery reaches its predefined value, CC charging stops. Mostly, this method is used for charging NiCd, NiMH and Li-ion batteries.

What can I use to charge my phone without a charger?

All of these methods require either a charging cable that’s compatible with your iPhone or Android device or a wireless charging pad.

1. Use a USB Port to Charge Your Phone.
2. Charge Your Phone With a Battery Pack.
3. Hand-Crank Chargers for Emergency Phone Charges.
4. Use an Eco-Friendly Solar-Powered Charger.

How can I make a mobile charger without electricity?

With that in mind, here are a few ways to charge your phone when there’s no power:

1. Eight D-Cell Batteries, Paper Clips, Some Tape and a Car Charger.
2. Plastic Bottles and Plates, Some Wiring, Rods, Other Odds and Ends (And Lots of Running Water)
3. Use Power Sources That Are Already Around You.

### Why is DC charging faster than AC?

Unlike AC chargers, a DC charger has the converter inside the charger itself. That means it can feed power directly to the car’s battery and doesn’t need the onboard charger to convert it. DC chargers are bigger, faster, and an exciting breakthrough when it comes to EVs.

Why is DC current not used in homes?

Direct current is not used at home because for the same value of the voltage, DC is more lethal than AC since direct current does not go through zero. Electrolytic corrosion is more an issue with direct current.

What kind of circuit is a cell phone charger circuit?

Cell Phone Charger Circuit. Mobile phones generally charge with 5v regulated DC supply, so basically we are going to build a 5v regulated DC supply from 220 AC. This DC supply can be used to charge mobiles as well as the power source for digital circuits, breadboard circuits, ICs, microcontrollers etc.

## How to make a cell phone charger?

There are basically four steps involved in making a cell phone charger. First step is stepping down the 220 volts of AC supply into small voltage. Second step involves rectification of AC into DC by using a full wave bridge rectifier.

How to use IC 7805 to charge mobile phone?

We can use ic 7805 to charge Mobile phone. But… Let’s see how to make it first. connect the charger line with the ic 7805 (detail in the video) Complete the connecting, connect the circuit, test the input voltage about 8.5V, The output voltage 5V.

How many volts is a USB phone charger?

USB Cell Phone Charger Circuit Schematic Most of the Mobile Phone battery is rated 3.6 volts at 1000 to 1300 mAh. These battery packs have 3 NiMh or Lithium cells having 1.2 volt rating. Usually the battery pack requires 4.5 volts and 300-500 mA current for fast charging.
