These equipments are designed to enable three functions in the lower dimensions, weight and costs :

• motor drive controller (synchronous, brushless, asynchronous)
• management of the all actuator system,
• digital output for man / machine interface.

This equipment accepts a variable frequency input. Active or passive filter reduces :

• courant harmonic distortion over the all frequency scale,
• voltage harmonic distortion over the all frequency scale
• reactive power consumption.
