Ericsson's Latest technology in Power Modules

Ericsson use the latest technology and highest standards of quality and robustness for achieving the highest system performance.

The products are primarily designed for advanced information and communications equipment, such as radio base stations and switches/routers, but they are also used in a wide range of medical, avionics, computing, military and industrial applications.

Every product design is the result of extensive research and development in power technology, broad application and system knowledge with a focus on design for environment and design for manufacturing, as well as efficient logistics and global support. The result is:

  • Low failure rate and long lifetime
  • Excellent dynamic load performance
  • High efficiency over a wide load range
  • Efficient thermal management

Ericsson offer more than 500 board-mounted products for a wide variety of applications.

They can be divided into:

  • Industry Standards Bricks
    • 1/16 - Bricks
    • 1/8 - Bricks
    • 1/4 - Bricks
    • 1/2 - Bricks
  • Surface Mount
    • Industry Point of Load

  • Industrial process control, etc.

Design for Environment (DfE)

Since year 2000 Ericsson have applied a design for environment (DfE) policy in all product development projects, including removal of hazardous substances according to the RoHS directive and a continuous development of designs and solutions for lower power consumption and lowest possible total cost of ownership for the end-user.

Ericsson PIM4300 Series

Telecom systems and many other applications require very low ohmic power distribution.

To handle short circuits and other power supply interruptions, a hold-up function is included on the majority of the boards in a system. Systems that have higher ohmic distribution or that use a central pre-regulator do not require this holdup function.

The Ericsson PIM 4300 quarter-brick format power interface module integrates all the features required by the AdvancedTCA specification (PICMG 3.0).

The Ericsson PIM 4300 series are power interface modules that supply output currents of up to 10 A. These modules are designed to be placed at the 48 V input before the DC/DC converter and include the supply, hold-up, and hotswap functions together with EMC filtering, protection, supply management, and an input supply alarm. Maximum output power is determined by the input voltage range.

The hold-up function provided by the PIM is designed to work with an external hold-up capacitor charged with an internally generated high voltage. This approach effectively reduces the size of the hold-up capacitor. When the hold-up function is activated, the PIM connects the hold-up capacitor to the input of the DC/DC converter.

This provides the energy that maintains DC/DC converter operation during the hold-up event, but also creates a voltage pulse at the DC/DC converter’s input. The capacitors in the application circuit should be designed to ensure that the hold-up function operates efficiently while limiting the voltage transient that may result in undesirable behavior of the DC/DC converter.

This application note presents a method for optimizing the component values and limiting the input voltage transient. It also includes a table with suggested values for different Ericsson DC/DC converters.
