Lithium ion cells packaged in aluminium cans continue to be the highest performing cells in the market. Circuit protection for rechargeable lithium-based battery cells and packs in a critical design consideration.

overcurrent and overtemperature conduction that can result from accidental shorting or abusive/runaway charging can raise temperature high enough to damage components and cause substantial damage.

PPTC circuit-protection devices are used to protect against harmful over current surges and over-temperature faults. Like traditional fuses, these limit the flow of dangerously high current during fault conditions. The PPTC device, however, automatically resets after the fault is cleared and power to the circuit is removed. Understanding the precise nature of these devices can help designers develop more reliable equipment and reduce warranty, service and repair costs. Improvements in size, cost and performance have resulted in wide spread ....etc

A prototype of a fully electronic on-load semiconductor tap changer for power transformer has been
designed and built. With the emergence of high power semiconductor devices, problems associated with the mechanical on-load tap changer have been properly rectified. In this work, the prototype was constructed with triacs as the switching devices and microcontroller as the triggering circuit. The results obtained from this work show that the prototype has a faster time response of approximately 0.44s to react to any load chang ....etc

Circuit protection for rechargeable lithium-based battery cells and packs is a critical design consideration. Overcurrent and overtemperature conditions that can result from accidental shorting or abusive/runaway charging can raise temperatures high enough to damage components and cause substantial equipment damage.
Early circuit-protection designs relied on fragile one-shot fuses to provide total current interruption for overcurrent protection. However, because the majority of f ....etc
