High-power loads heavily tax the 12V system in current heavy-duty and super-duty passenger trucks, and these loads are key for the consumer to effectively use their vehicle. Converting these loads to 48V creates a diffusion of responsibility between OEMs and aftermarket suppliers. Who owns this conversion? As these trucks make the switch to a 48V architecture, how will the aftermarket suppliers respond? What should you be thinking about now to make the transition easier in the near future? What is the best approach now that can future-proof the ongoing transition to 48V? Flexible, scalable, and power-dense DC-DC converter modules are a key to a smooth migration for both the OEMs and aftermarket players.
