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.

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

Test inverter PWR

Test inverter PWR-100

The test inverters of the PWR series from EAAT are inverters that have been specially developed for testing electric motors in a wide variety of power classes as well as current and voltage levels.

Possible uses:

  • Parameter identification
  • Endurance and heating tests
  • Determination of characteristic fields

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
