Dinesh Wick posted a topic in Power ElectronicsHello Everyone, I am trying to build a mobile phone charger (For my Samsung phone) by myself using following components. Step down transformer (from 230V to 9V 1200mA) Bridge Rectifier 1000uf capacitor (To smooth the DC voltage) 7805 Regulator (To get output voltage 5V) A micro USB cable I got from a broken charger.
