"The biggest change in power over the last five years is probably the attention that people pay to energy efficiency. That’s given the power industry back some respect that it didn’t have some time ago,” said Conor Quinn, director of technical marketing at Artesyn Embedded Technologies. The company is one of the largest power supply companies in the world, consistently ranked in the top three in revenue with a long legacy, through ASTEC and the acquisition of the Motorola Computer Group and Force Computers.
The AC-DC product portfolio covers a power range of 3 W to 24 kW and includes open-frame and enclosed models, highly configurable modular power supplies, rack-mounting bulk front end units, DIN rail power supplies, external power adapters and power supplies for LED lighting. The isolated DC-DC converters cover sixteenth- to full-brick form factors and power ratings from 6 to 800W and three application-optimized families of non-isolated DC-DC converters. Headquartered in Tempe, Arizona, Artesyn has over 20,000 employees worldwide across ten engineering centres and four factories.
“There’s always the perception that power is the last thing that people think about but nowadays there’s more talk of power at the system level and a lot of that is driven by energy efficiency and standards to meet government regulations,” said Quinn. “That is the biggest change that has happened and continues to happen, starting at computer and moving through into the other spaces.”
This is a big change that impacts on the design teams and product specifications, he says. “It has changed the makeup of the design teams - there’s a lot more digital expertise. We have been shipping digitally controlled products for over ten years as one of the early movers in this space. Early on the digital assisted the analogue, then it was replacing the analogue functions and now the vast majority above a certain threshold are fully digitally controlled. We are pushing the power levels that use digital control down
