    42v switch mode-based charger for advanced vehicle
    (UMT.Lahore, 2016) Saad Abdul Basit; Syed Irfan Hayder; Muhammad Zuhair Ammar; Muhammad Naeem Waris
    As the demand in electrical loads increases in today’s advanced vehicles, there is a need to replace current 14V system to a new voltage system because the current system is not enough to meet the load requirement. To resolve this problem, an efficient and cost effective switch mode based 42V battery charging system using flyback topology is designed. TL494 PWM controller is used to design gate drive circuitry. Design is first simulated on NI Multisim software. Then, it is tested practically by connecting three 12V/ 4Ah batteries in series. Final converter circuit is successfully charging the batteries as desired. Keywords: battery charger, low cost, new voltage system for advanced vehicles, flyback, SMPS, TL494
