Modern computing systems, particularly in data centers, can have a high ratio of peak to continuous power draw. DC/DC converters providing power rails can match this with continuous and peak current ratings but must be monitored closely to avoid over temperature stress.

Board mounted DC/DC converters can now be rated in kW and even with high efficiency levels, they dissipate significant power. Cross coupling of heat from loads and other components in close proximity means that prediction of the DC/DC internal temperature rise is not simple.

In modern computing systems, loads are often dynamically changing with high peak to average ratios. To reduce unnecessary costs and to save space, DC/DC converters can be specified with limited peak power ratings to cover these conditions. To avoid stress, DC/DCs must have secure over-temperature immunity.

Artificial intelligence or AI as a process is placing extra loads on datacenters, both in computing throughput and in energy consumed. As a result, provision of power with maximum efficiency is a major consideration along with power density of the power conversion hardware

For telecom and datacom centers, power requirements are always growing. More and more processing performance is being squeezed into racks, and power supplies need to keep up. Read more about these challenges and how we solve them.

In power distribution systems, use of an intermediate bus is a way to achieve a best compromise between losses and practicality. The “ideal” bus voltage has varied over the years as conversion and semiconductor technology has advanced.

There has been increasing concern about ‘halogens’ in electronics -continue to read the blog and find out more.

Powerful DC/DC solutions for robotic applications.

Mounting DC/DC power modules vertically rather than horizontally can free up board area in space-constrained applications without compromising performance. This blog looks at some options.

Semiconductor switch technology promotions are a maze of claims for best efficiency and cost-effectiveness. There is a place for them all, from the humble IGBT through silicon- and silicon-carbide MOSFETs to GaN HEMT cells. Depending on your development schedule, application and budget, each technology can give excellent results. This includes the gate drive which is critical for best performance, both in losses and reliability for all the device types.

There are established ways to generate power rails for end-loads in data centers, but a novel combination of conversion technologies can be used for efficiency, cost and power density gains.

Evaluating the reliability and availability of data center services hinges on performance monitoring. Latest power converters provide valuable real-time data with built-in ‘event data recorders’ - so called ‘black-box’ recording functions
