While gate driver-based converters deliver improved efficiency, speed and signal integrity, their high frequency switching features can produce elevated levels of conducted electromagnetic interference (EMI), posing challenges to electromagnetic compatibility (EMC) and overall system reliability. To solve this

Reducing demand for energy on the battlefield is a key challenge facing many U.S. military forward operating bases (FOBs). Tactical generators consume millions of gallons of fuel keeping FOBs up-and-running each year. Safe and reliable access to fuel to power each generator is important to the success and security of

Rapidly growing demand for data capacity means that data center power requirements are increasingly reaching megawatt rather than kilowatt levels. Let’s looks at how UPS providers can respond to this challenge while maintaining the availability and energy efficiency standards enjoyed by lower power installations.
Data centers a

U.S. commercial businesses spend over $100 billion on energy annually with much of that consumption coming from building systems such as HVAC, lighting, security, elevators and fire protection. For example, in a commercial building, lighting alone can account for almost 35% of the total energy used. Experts es
