Power electronics from EAAT
Frequency converters, inverters and AC/DC sources according to your requirements

One of the first and still most important pillars of EAAT is the development of customer-specific power electronics. Since the company was founded, i.a. current and voltage sources are developed and manufactured, as well as frequency converters, from which the first series production later emerged.

With our solutions, we always offer our customers the added value they need thanks to the use of modern technologies and algorithms.

Our engineers look forward to your inquiry.

Advantages of power electronics from EAAT

EAAT's power electronics offer customers solutions in the form of frequency converters, inverters and AC/DC sources, in which modern chip technologies and control algorithms are used. The customer's requirements are always in the foreground.

A large number of topologies are implemented in our solutions. They are characterized by high performance, flexibility and reliability.

 

Product examples

Motor-integrated frequency converters

Motor-integrated frequency converters

Due to their high compactness, our motor-integrated frequency converters can be integrated axially into the electric motor case. You are able to control a wide variety of motor types (BLDC, PSM, ASM, reluctance motors, etc.). In addition to sensor-based control algorithms, it is also possible to control the electric motors without sensors.

Possible uses:

  • Fans for stationary and mobile applications
  • Pumps
  • Compressors

Current sources/voltage sources

Voltages sources

Our current sources/voltage sources are primarily used in test fields. They often serve to simulate international grids. Furthermore our current sources/voltage sources are also used in laboratories, e.g. in the generation of magnetic fields.

In addition to our portfolio of standard devices in the 45 to 70 Hz range, we offer customer-specific solutions in almost all performance classes.

Possible uses:

  • Simulation of international networks
  • Generation of magnetic fields in the low and medium frequency range
