Zusammenfassung:Two different adaptive gate control methods were developed recently to improve EMC of SMPCs with fast switching Power-MOSFETs. These successively working methods take advantage of compensating driver delays and therefore are able to actively control the current and voltage slope during switching as well as to minimize deadtimes. But there are some constraints when used in applications with highly dynamic drives. This paper analyses the effects of varying load conditions on the successively working methods and proves the operation of the control methods in a brushless DC motor application.
