Flyback Topology Highlights and Bourns Solutions for Low Power Conversion Drivers
Flyback operation is an energy storage topology operating in single quadrant operation of the magnetics BH material loop. The goals of this module are to explain how unavoidable parasitic components of transformer design affect leading edge transient behavior for this topology. In addition, how gapping is used to control the overall size of the transformer and tradeoffs involved between core size and saturation current handling. Bourns catalog flyback transformer solutions will be presented for various types of IC chipsets and generally what input requirements are needed to effectively design the transformer.

Attendees of this training module will learn:

• Magnetics design involves multiple design tradeoffs
• Tradeoffs affect the overall size and performance of the component
• Effects of core gapping need to be considered
• Safety and isolation play a large part of the design process in a given application
• Automotive requirements can be a special case (BMS for example)
• Separation requirements between low voltage and high voltage can be implemented several ways – typically by the transformer
• Bourns offers a multitude of flyback transformer solutions

The latest revision of IEC standards increased the voltage used to test MOVs. This accelerates thermal runaway in MOV components, requiring the designer to consider preventive ways to avoid this failure mode. Attendees will learn all the critical aspects of these IEC standards that affect their designs including IEC 62368-1. The webinar will also discuss how to upgrade MOV overvoltage protection to include the benefit of GDT isolation to meet this new IEC recommendation. Pin compatible solutions – including Bourns’ groundbreaking new IsoMOV™ Hybrid Protectors – are available that do not compromise performance, size, or cost.

The growth in the electric vehicle, industrial, marine and home energy storage markets is being propelled by the use of high-energy battery packs. These packs require battery management systems (BMS) with precise current measurement to monitor and maintain battery cells in good condition, to maximize output power, maintain safety, and offer accurate State of Charge information.

This webinar will present resistive current measurement solutions from Bourns, digging into design considerations, error sources and implementations that will help BMS designers to improve current sensing accuracy.

Furthermore, an overview of the Bourns standard and custom Power Conversion portfolio as well as the company’s Circuit Protection component lines optimized for BMS designs will be provided.
