WebEven so, on occasion, designers find the need to operate two MOSFETs in a parallel configuration. Generally speaking, as MOSFETs do not suffer from thermal runaway (as can happen with bipolar devices), this makes paralleling them easier. As MOSFETs are voltage-driven, they simply need a stable and uniform voltage. WebWith the rapid development of the electric vehicle (EV) industry, charging facilities for electric vehicles are gradually improving, thus meeting the demand for fast and safe charging. This paper comprehensively describes the current development status and future development trend of EVs and their charging infrastructure and analyzes in detail the EV …
