Power Supply Manufacturers and the Importance of Promoting Power Supply Efficiencies

What are the Power Supply Manufacturers Roles

Let’s face it, with the economic and environmental turmoil that is facing this nation, this world, power supply manufacturers are playing an integral role in improving the effectiveness and pollution reduction of all forms of electronic equipment. Simply put, power supply manufacturers are redesigning electrical apparatuses so that every possible input of energy is utilized to the full extent without very much waste.

For example, the most current advancement in power supply technology has been the implementation of digital-controls. As a matter of fact, numerous power supply manufacturers have launched new digitally controlled power supplies for a myriad of applications. Furthermore, with microcontroller-based digital control, power supply manufacturers are able to produce power supplies that are smaller and much more efficient when compared to their predecessors. As a result, this trend contributes positively to the global movement towards a “greener” and earth-friendlier electrical line of products.

Power Supply Manufacturers and Power Supply Efficiency: There are No Boundaries

The productions of digitally controlled, power-efficient products created by conscientious power supply manufacturers really know no bounds. Their adaptations can be applied to the medical, industrial, and commercial specifications – especially in places where space is limited, as these products provide a smaller and cooler (and thereby more efficient) product. In fact, many of these innovative new designs, pioneered by power supply manufacturers, include integrated magnetics and inductor windings that are wound on the same magnetic core for efficiencies of greater than 90%. In addition, to further enhance their proficiency, power supply manufacturers have produced these power supplies using small microcontrollers that replace the bulky and less efficient analog circuits

Why Have Power Supply Manufacturers Placed an Emphasis on Digital Control?

It’s simple: digital control is necessary to regulate the dc outputs and handle routine tasks that are inherent to all power supplies. For example, the Power Supply Manufacturer, by producing digital control, reduces parts count by 25%, size by 45%, and weight by 56%.

In addition, digital power supplies include an active power factor correction. This guarantees EN61000-3-2 compliance from a wide-ranging input range (from 90 ? 264 V ac for global applications). Furthermore, earth leakage current can be less than 300uA at up to 264-V ac input ? essentially complying with most medial safety requirements.

What Other Design Features Have Power Supply Manufacturers Implemented Due to Digital Control?

Power supply manufacturers have developed other electromagnetic compliance and efficiency-improving designs that include:

  • The use of low-loss silicon-carbide Schottky diodes that ensure conformance with EN55022 Class B EMC.
  • The new digital power supplies can be certified per the IEC/EN/UL 60601-1 standards for medial equipment.
  • The new digital power supplies can be certified per the IEC/EN/UL 60950-1 for general purpose and industrial applications.
  • The new digital power supplies can be certified per the IEC/EN/UL 61010-1 for laboratory and process control applications.
