With the increasing market for electrified vehicles (EVs), the demand for onboard chargers (OBCs) is growing fast. OBCs open up the possibility to charge the car at fast-charging DC stations and with AC sources in a reasonable time. Such systems are currently going up to 22 kW with operating voltages up to 800 V.

Switching DC-DCs regulate the output voltage based on energy flow into and from the DC-DC by controlling the duty cycle of the on and off states. When the switch is conducting, energy flows from the input source into the converter and in the case of a buck, some of this gets stored in the inductor as magnetic energy (0.5*LI2) while some gets delivered directly to the output (forward topology).
