The electric vehicle (EV) charging market is very dynamic. Companies and institutes involved in the research and development of this area are devoted to considerably reduce the EV charging times to be close to the ones spent by users in gas-stations filling the fuel of the internal combustion engines vehicles. Today most EVs can be charged at 50 kW and 400 V following the fast-charging standards "CCS - up to 80kW However new EVs are designed to withstand higher charging power. Therefore, output power scalability will be a key feature of the EV charging system by usage of power electronics buil...
The electric vehicle (EV) charging market is very dynamic. Companies and institutes involved in the research and development of this area are devoted to considerably reduce the EV charging times to be close to the ones spent by users in gas-stations filling the fuel of the internal combustion engines vehicles. Today most EVs can be charged at 50 kW and 400 V following the fast-charging standards "CCS - up to 80kW However new EVs are designed to withstand higher charging power. Therefore, output power scalability will be a key feature of the EV charging system by usage of power electronics building blocks, i.e., the total power can be scalable by paralleling circuits. This leads to manufacturing advantages because a single circuit building block design can satisfy a plurality of business and many charging standards. one can identify a well-known two-stage power conversion system, i.e., a three-phase AC-DC converter, a DC-DC circuit. The back-end circuit works as a three-channel PWM interleaved DC-DC buck-type converter. This features enhanced loss distribution among semiconductors or better current shared between the parallel circuits than hard paralleling of semiconductors.
