Custom Power Platforms

Micropower Group have delivered more than 8 Million power supplies and chargers during the past 35 years. A majority of these units have been manufactured through our more than 25 years of experience with factories in Asia. 

This gives us an unique experience and capability of combining Nordic product management and development with cost efficient Asian manufacturing for high volume. With our Nordic located factories we can also offer power solutions where high mix and low volumes are required. 

Each design delivered to our customer is based upon a design platform which is reused as basic starting point when new custom specific power products are developed together with our customers.

Custom Platform Concept

Innovations and the development of platforms are used through-out Micropowers complete product range and through our OEM/ODM custom power offerings. 

Benefits of using a platform based development approach are:

  • Shorter leadtime in development.
  • Reuse of already proven technology.
  • Flexible for customized variants with low effort.
  • Reuse of existing production processes.

With the custom power offerings all the custom power platform benefits are made available to our customer. Customization can range from full custom design to use of existing certified platform product where color, branding, cable or software is customized.

Unique features of the Micropower custom power platforms

Our custom power platforms are technology platforms with high degree of reuse and modularity. They are established through our innovation process and contains our unique solutions for high frequency switched power conversion. All platforms can be fully analog or digital controlled and can modular scale from power supplies to chargers by just adding a charge control function to the power supply. This scaling between power supply and charger functionality requires a wide regulation capability in the high frequency switch which are included in our own unique switching technology. Demanding application specifically appreciates the high peak power capability and the always on functionality where the output power gracefully decline in overload situation vs the more common instant shut down of output power. These feature are highly appreciated in medical and industrial applications and essential in applications such as audio, motors or linear actuators.


AC/DC Power Platforms

Ac/dc power platforms has long been the fundamental of our power conversion offerings and thus the range in offerings are wide including single phase or 3-phase systems between 30W to 12KW. 

AC/DC power platforms include one step conversion with passive PFC from 80W to 450W and two step conversion with 

active PFC from 150W to 12KW. One step conversion provides significant reductions in component count and cost efficiency while 2 step provides greater flexibility in optimizing the conversion in multiple domains. 

Our AC/DC power platforms have high to ultra-high efficiency and supports the toughest EMC requirements in medical, industry and defense applications. 


DC/DC Power Platforms

Our dc/dc power platform includes both fully galvanic isolated and non-isolated power conversion in the range from 60W to 1500W. Our dc/dc power platforms come in multiple input and output ranges with a minimal footprint through high usage of surface mount technologies. Surface mount is also used for our isolated dc/dc power platforms

where the isolation barrier use surface mountable or PCB integrated planar transformers. Our non-isolated dc/dc power platform offers lower cost, higher efficiency, and greater output power with simplified cooling. These non-isolated devices also can operate from wide input ranges and have very wide output adjustment. With or without isolation our dc/dc power platforms will meet the highest efficiency requirements. Together with the integrated filters and input protection a compact custom specific dc/dc converter can be realized or used as a building element in a complex power solution.    


Digital Power Platforms

Our digital power platform with a range from 150 W to 1500W provides a robust AC/DC platform for power supply and chargers. It is ideal for demanding industrial power supply and charging applications but can also easily be customized for other environments. The digital power platform offers several benefits including easy customization, high energy efficiency optimization, external communication / configuration and material cost reduction via functional integration. 


Mobility Power Platforms

Our mobility power platforms provide power both when connected to a power grid and off grid through the integration of power storage elements. This combined solutions includes charging capability (on-grid charging through AC/DC charging or off-grid charging through DC/DC charging), multiple output power sources (through DC/DC converters), battery management  and power control system, communication ( wireless, NFC, CANopen, LIN, I2C and/or customer proprietary protocols) and our own Li-Ion batteries or customer specified batteries.  Power storage capabilities in the mobility power platform can be in the range from 50Wh to multiple kWh.
