IGBT Gate Boost Drive Technology for Promoting the Overload Capacity of Traction Converter

open access: yesMicromachines
Under certain circumstances, a high-speed railway may require constant acceleration or emergency braking, in which case the inverter may experience short-term overload conditions and the current passing through the IGBT will go beyond the rated design ...
