INSIDE A MOBILE PHONE CHARGER(FLYBACK CONVERTERS) MaziTek Electronics
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. Since the DC voltage obtained in second step, contains AC ripple which is removed using filtration process.
