    On/off-board 42v switch mode-based charger for advanced vehicles
    (Electrical Systems for Aircraft, Railway, Ship Propulsion and Road Vehicles, 2015) Nauman Ahmad; M. Omer Abid
    With the ever increasing demand of electrical loads in vehicles, shifting towards a new voltage system is inevitable as current 14V system is not meeting the needs. An efficient and cost-effective switch mode-based 42V on/off -board battery charger system using push-pull topology is designed. Pulse width modulation (PWM) based feedback circuitry is employed to regulate the output voltage. Circuit is simulated first, before implementing practically. Circuit is tested successfully by charging three 12V batteries connected in series. Final converter was able to produce and regulate the voltage to 41.6V which is enough for charging.
