Artesyn’s configurable power supply range delivered
Choosing the power supply for a project can be a challenging process. Prototypes cannot be developed without a supply of power, but the exact power requirements may change as the project progresses. It can be wise not to commit to power supply decisions too early.
On the other hand, an off-the-shelf PSU that

Powerbox GB350 digitally controlled power supply for applications operated under high electromagnetic field
The overall market for AC/DC and DC/DC commercial switch mode power supplies (C-SMPS), which excludes consumers and uninterruptible power supplies (UPS), is estimated to be in a range of 22 to 25 billion US Dollars. This level has been stable for more than five years and from an outsider’s point of view, could be p

Forward converter output filtering
Most modern power conversion topologies use switched-mode techniques for highest efficiency and smallest size and cost. Inevitably, switching noise is produced and output filters are required to minimize EMI and provide reliable operation of the power converter and load. This article looks at some filtering te

MAX14001 simplified functional diagram
Measuring high voltages (12V to 300V) and currents using a low-voltage microcontroller is a growing requirement in industrial automation equipment. For example, a low- voltage microcontroller system can be used to monitor high-voltage industrial equipment for an unstable AC or DC power supply. This protects eq

Use your PC to set the dimming values, and see the results.
RGB LEDs are used in projector, architectural, display, stage and automotive lighting systems that require efficient, bright output. To produce predictable colors from an RGB LED, each of its component LEDs (red, green and blue) requires individual, accurate dimming control.
High end systems can use an optica

SL Power Supply
The main value propositions for LEDs over traditional lighting are twofold: Long life expectancy that translates to saving money on replacement costs, and higher illumination using less energy to lower electricity bills. Due to the solid state nature of LEDs that require electronic circuits to emit light, the th

Proximity sensors in a factory environment
Sensors play a major role in enabling Industry 4.0 applications, but their underlying electronics are complex. On-board voltage regulators are typically needed to deliver power more efficiently with minimum heat generation. One big challenge, however, lies in safely delivering low voltage power to these tiny se

Designing for safety, speed, and cost-efficiency in PV inverters
No longer is solar energy an emerging technology, but rather a rapidly maturing one that is undergoing momentous technological changes. The goal of grid parity—where the cost of solar power matches and, indeed, improves that of traditional energy electricity generation types—is getting closer, as the conversion of

Innovative Topology Overcomes Conflicting Piezo-Driver Requirements
Piezoelectric elements have traditionally been used primarily in applications in the audio industry, operating in the human audio range (nominally 100 Hz to 18 kHz). However, subsequent improvements in device characteristics have extended their usefulness into markets which demand much-higher performance. For ex
