Overload protection in digitally controlled DC-DC converters

Abstract: This paper presents an approach to overload protection based on a predictive average current-mode control technique for digitally controlled DC-DC switched-mode power supplies. The proposed approach can be applied in voltage-mode or current-mode control architectures. The current limit, the converter actions upon detecting an overload, and the shape of the overload characteristic can be fully programmable. Static and dynamic operation are discussed and the results are verified on a digitally controlled 6V to 1… Show more

“…However, it was designed especially for the variable speed AC and DC drives, not suitable for general cases. A predictive average current-mode control technique in digitally controlled DC-DC switched-mode power supplies was proposed for overload protection, but it was only suited to a low-power case such as 1.8-6 V with 10 A [18]. An overload protection model based on heat effects was developed using motor internal temperature-rise model [19].…”
