This paper will discuss an ultra-functional circuit that can be used in a variety of applications, including Electric Vehicle (EV) charging. It can be used in different modalities, such as On-Board Chargers (OBC), offboard wallbox chargers or wireless chargers. Although the main function of the circuit is to transmit a constant DC power to the output due to the filtering capability of the circuit, it can also perform other functions such as peak shaving or Low-Voltage (LV) battery charging.
