How do variable voltage chargers work?
The charger probably uses a fast switching transistor and diode to rapidly switch between the input voltage and ground, then an LC filter to smooth out the switching and output the average voltage. The resulting transfer function is Vout=D*Vin, where D is a PWM duty cycle.
What does a mobile charger contains?
A battery charger consists of a rectifier circuit, power circuit, ripple monitoring, control circuit, regulator circuit, and fault detection circuit. This charger can also be used as a DC source for a control and protection circuit of a substation during normal operation, or to charge the battery in floating mode.
What is the difference between mobile charger and normal battery charger?
For the reason of smaller in size, the mobile charger has a different charging circuit than a normal battery charger circuit. Modern mobile chargers work like SMPS (Switch Mode Power Supply). This type of charger can work at 110v-230v, 50Hz-60Hz.
How does a modern mobile charger work?
Modern mobile chargers work like SMPS (Switch Mode Power Supply). This type of charger can work at 110v-230v, 50Hz-60Hz. The working of a simple mobile charger described step by step below. We have described the working of the mobile charger circuit which shown in below picture.
What is a mobile cellphone battery charging circuit?
Mobile Cellphone Battery Charging Circuit with Explanation. A mobile battery charger circuit is a device that can automatically recharge a mobile phone’s battery when the power in it gets low. Nowadays mobile phones have become an integral part of everyone’s life and hence require frequent charging of battery owing to longer duration usage.
Why do you need a battery charger for your mobile phone?
Nowadays mobile phones have become an integral part of everyone’s life and hence require frequent charging of battery owing to longer duration usage. Battery chargers come as simple, trickle, timer-based, intelligent, universal battery charger-analyzers, fast, pulse, inductive, USB based, solar chargers, and motion powered chargers.
