Miba Power Safety Devices

Power electronics for eMobility applications. For greater safety in the event of a collision.

Miba POWERfuse® Emergency disconnect for HV vehicle batteries

In the event of a technical malfunction or accident, the Miba POWERfuse® disconnects the battery quickly and safely from the vehicle's high-voltage electrical system. This disconnection is triggered both by a signal from the vehicle safety control system and by an integrated self-release mechanism.

Product details


Miba POWERcloser® Emergency stop switch for HV applications

The Miba Powercloser® is an electrical safety switch. It reliably closes circuits that could pose a hazard to the system or people. The switch is triggered by a pyrotechnic actuator. The switch-off is fully automatic. 

Product details

Miba Pre- and Discharge Resistors

Miba high-performance resistors for the for the eMobility industry are used as precharging resistors in battery distributors for precharging the DC link. Special thick-film resistors for fast and safe discharge of the DC link on DC-AC inverters in the powertrain are among our core competencies.

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, EBG 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 EBG 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. EBG resistors are therefore manufactured according to individual customer requirements.


DAU 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.
