A CHARGING CIRCUIT IS COMPOSED OF THE FOLLOWING STAGES OR SECTIONS:
1. Battery Charger Circuits - Although this is not found on mobile phones PC board circuit and have separate circuit but definitely this is also part of charging circuit; without this, the charging circuit is not complete and will not work completely.
This circuit is all parts and components that being mounted on any mobile phone charger, this is the one that converts AC (Alternating Current) voltage to DC (Direct Current) voltage.
What is AC Voltage? This voltage is a power source that we used in our household appliances to work and operate, this voltage can cause risk of electric shock and very dangerous to humans when being touch. This kind of voltage has an alternate polarity.
What is DC voltage? This voltage is a low level voltage which typically found on any kind of batteries.
These kinds of voltage have two polarities, the negative and the positive.
