As electric vehicles (EVs) become more mainstream, the demand for faster, safer, and more efficient charging systems is growing rapidly. At the heart of these systems lies a critical component known as the On-Board Charger (OBC). The OBC plays a vital role in converting AC power from a charging station into DC power that can be stored in the EV’s battery. One of the key elements that ensures the smooth and efficient operation of OBCs is the IGBT module​, and specifically, the 20A 100V SBD IGBT module has emerged as a preferred choice for many modern OBC designs.
