At Miba, power electronics stands for innovation, efficiency and a clean future. Our products and technologies offer customised solutions for renewable energies, eMobility and industrial applications.

 

Miba Power Electronics
Power Electronics for eMobility applications

Miba is a key partner in eMobility. Our components contribute to the development of sustainable and safe mobility solutions. This is because they maximise the efficiency of the power electronics in electric drives and extend the service life of the overall system.

We offer a comprehensive portfolio of charging and discharging resistors as well as power safety devices such as our pyroswitch Miba POWERcloser®.

 

White precharge resistor
Miba PREcharge Resistors

Miba high-performance resistors for eMobility applications are used as pre-charging resistors to pre-charge the DC link in battery distributors reliably and efficiently. These resistors ensure stable and safe commissioning of the power electronics systems.

Product Details 

Black bleeding resistor
Miba DIScharge Resistors

Our special thick-film resistors enable fast and safe discharging of the DC link in DC-AC inverters in the drivetrain. They make a decisive contribution to the safety and reliability of the entire eMobility application.

Product Details 

Yellow blue pyroswitch
Emergency stop switch for HV applications

The Miba POWERcloser® is a reliable electrical emergency stop safety switch for high-voltage applications. Triggered by a pyrotechnic actuator, it automatically closes dangerous circuits to protect both the power electronics and people.

Advantages of Miba Power Electronics

More safety, reliability and efficiency for eMobility applications. With Miba power electronics you benefit from numerous advantages:

 

Maximum precision in the manufacturing process
The production of our power electronics components is fully automated from the receipt of raw material to the finished product. Our state-of-the-art facilities feature automated material printers, soldering machines, wire bending machines and much more - all carefully linked together in a pristine clean room environment to ensure the highest level of quality.

 

Longevity of our resistors
Our resistors are designed for up to 300,000 pre-charge or discharge cycles. Thanks to high-quality materials and precise manufacturing techniques, they can withstand extreme loads. Our resistors offer stable performance over their entire service life, resulting in reduced maintenance costs and increased operational reliability.

 

Certified power electronics
Miba is certified according to ISO 9001 and IATF 16949. Our products are AEC-Q200 compliant and meet automotive standards. Industry standard documentation such as PPAP is available on request.

 

Suitable for series production
Miba develops safety components that are not only powerful, but also optimized for series production. This makes them perfect for integration into mass-produced vehicles to ensure the performance of eMobility applications on a broad basis.

Frequently asked questions about power electronics

Power electronics transform various types of electrical energy. The voltage level, frequency and the number of windings per string are adjusted. The areas of application for power electronics include aerospace, manufacturing and process automation, the generation and transmission of conventional and renewable energies, and electromobility.

 

Depending on the product group and type, Miba resistors are certified according to specific, recognized standards:

  • AEC-Q200 compliant 
  • MIL-Standard
  • UL

For information on the respective product certification, please refer to the data sheet, which is available as a PDF download on the respective product page.

In order to estimate the lifetime of electronic systems, a variety of thermal and mechanical measurement and calculation methods are used. With proportional operation, the service life of Miba resistors is more than 30 years.

 

The increasing individualization of products and the ever-growing share of power electronics require maximum flexibility in the production of different assemblies. Miba resistors are therefore manufactured according to individual customer requirements.

 

Miba Cooling manufactures heat sinks from the materials aluminum, stainless steel, copper and CuNiFe. Depending on the material, different cooling media are required for a water heat sink.

 

Depending on the respective requirements, the optimal cooling solution is selected. The possibilities are besides air cooling:

 

  • Vacuum-brazed heat sinks with integrated heat pipe function (VBA-HP).
  • Integrated heatpipes in the air cooler
  • Water cooler

The performance depends on the following factors:

  • Available volume flow of the medium used and its mixing ratio.
  • Pressure drop in the channel run / in the channel structure (flow field) under the electronic component to be cooled.
  • Selected manufacturing technology of the KK (for example, a vacuum-brazed heat sink is ideally tailored to the power electronics component to be cooled.
