Simplifying field-side circuitry

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

Converter and inverter output filtering

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

The state of the power industry

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

Optimizing power design with configurable modules

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

Increasing inverter efficiency

Complete motor inverter for a power output of up to 150 kW.

TDK has joined forces with Infineon Technologies to develop a design for xEV inverters that achieves a very high efficiency of over 98% over a power range of 10 kW to 150 kW. This success has been achieved by matching of the Infineon IGBT module and the EPCOS and TDK passive components. The new Infineon

LED Applications Require LED-Specific Power Supplies

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

Tightening energy efficiency standards

Infographic: The evolution of energy efficiency standards from 2004 through to the latest 2016 US DoE Level VI regulations and the impending EU CoC and Ecodesign requirements (Courtesy of CUI Inc.)

Just when you thought you had it nailed, along comes another set of energy efficiency standards for external power supplies. Yesterday’s standards are no longer good enough and manufacturers cannot afford to be complacent. Meeting energy efficiency standards is not a one-time fix. The pressure on

Using an LED matrix dimmer

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

Driving piezoelectric elements

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

Next-gen solar power conversion

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
