A new fully integrated power module for three phase servo motor driver applications

Today´s solutions for motor control applications require more flexibility and a higher level of integration that could be achieved only through specialized products. This paper presents the analysis of the first results obtained from a new family of intelligent power modules developed specifically for servo motor drive applications. The module´s architecture includes several key design features needed in these applications, such as motor phase current sensing, DC bus voltage control and short circuit protections while the embedded DSP allows easy realization of the current loop and even speed loop at the module level without any external components.
