Learn why flyback transformers are well-suited for low power offline converters used in applications such as smart meters, LCD displays and small appliances. Implementing a flyback design allows higher output than a buck configuration. Bourns provides design considerations that include the calculations involved in selecting the primary inductance as well as the number of primary turns for a transformer.
Current sense resistors help motor control system designs benefit from adopting new digital isolation technologies. Bourns offers recommendations for selecting the best current sense resistor for this application. The paper presents the standard differences between traditional opto-coupler-based technologies and inductive/capacitive technologies for reinforced isolation, and provides a system overview that uses digital control of a motor drive.
Overtemperature/overcurrent threats are growing concerns in higher capacity batteries that have greater stored energy. Short circuits or deep discharges can increase temperatures in the battery cell to levels high enough to cause damage not only to the battery cell itself, but to other components.
