Fast battery charger for Electric vehicle
  The fast battery charger is composed of AC-DC PWM converter and DC-DC converter. The aim of the fast charger is to convert AC source of the grid to DC source quickly and efficiently. For medium-power and high efficiency, NPC 3-level inverter and phase shift full-bridge converter is used. The switching loss is small because the voltage variation of the power device is half of the DC-link in NPC 3-level inverter. Phase shift full-bridge converter regulate wide output voltage and the switching loss is very small by ZVS operation.
