Dead Time Volt-Second Compensation of Converters Enabled by 10 kV SiC MOSFETs
2023 25TH EUROPEAN CONFERENCE ON POWER ELECTRONICS AND APPLICATIONS, EPE'23 ECCE EUROPE(2023)
摘要
This paper highlights the increased importance of volt-second compensating converter non-linearities such as dead time for wide bandgap semiconductor devices utilized in medium voltage converters. The increasing voltage level of medium voltage converters impose a penalty to the volt-second compensation required to compensate for the voltage error caused by dead time. A thorough analysis and experimental results of switching events are utilized to present the required volt-second compensation for a 10 kV silicon-carbide MOSFET power module.
