Circuit breakers are now standard household equipment that protects electrical systems from fire and overcurrent. This protective switchgear saves lives, time, and money for power system maintenance. This article explains circuit breakers in detail along with their working principle, types, uses, applications, replacement, and tests.

Ensuring the longevity and reliability of components is crucial for maintaining efficient and stable systems. One critical element that contributes to this goal is the snubber circuit. This article explains the construction, functionality, and most common applications of snubber circuits and also highlights alternative protection methods used in modern electronics.

“Moore’s law is dead!” This is a line of thought championed by many prominent individuals in the fields of electrical and power engineering. But it’s quite a controversial one; just as many people believe Moore’s Law is still true today in 2024 as those who believe that it’s dead and no longer valid.

There are broadly three types of static, or solid-state, uninterruptible power supplies available: Off-line, line-interactive, and on-line. Here, we look at these topologies and their relative merits.

An international research team is investigating ways to better plan for climate-resilient energy systems in the Global South. Focusing on the case study of Accra, the capital of Ghana, the multidisciplinary team expanded conventional energy system modeling approaches by incorporating a range of socio-techno-economic challenges, climate change impacts, and resilience metrics into their models. Their approaches are applicable worldwide to support widespread sustainable and resilient energy system transitions.

VisIC Technologies Ltd. has partnered with Heraeus Electronics and PINK to develop an advanced power module utilizing D3GaN technology. This power module is based on a silicon nitride ceramic substrate, an innovative silver sintering process and advanced top side interconnect, promising unprecedented reliability and performance for battery electric vehicles.

Electromagnetic Compatibility (EMC) ensures the efficient operation of electrical and electronic devices, equipment, and systems within their intended electromagnetic environment. EMC tests are run to check whether a system emits electromagnetic radiation or is affected by it. Without EMC, electrical and electronic systems are prone to failure and damage. The article discusses 12 ways to improve EMC performance.

Invented in 1902, the mercury-arc rectifier made it possible to supply high-voltage direct current (HVDC) for major operations, such as powering radio transmitters and the New York subway network. Although mercury-arc rectifiers were gradually phased out in the 1970s, their legacy is proving extremely valuable for the renewable energy sector.

Heat pumps are becoming essential for energy-efficient heating and cooling. onsemi's advanced components optimize these systems, enhancing efficiency, reliability, and environmental sustainability.

Supercapacitors are used to store large electrical charges, which opens up a wide range of applications. What exactly these are and how supercapacitors differ from batteries, is explained in this article.
