This paper introduces a novel maximum power point tracking technique aimed at maximizing the power produced by photovoltaic systems. The largest part of the approaches presented in literature are based on the sensing of the photovoltaic generator voltage. On the contrary, in this paper a current-based technique is proposed: the sensing of the current in the capacitor placed in parallel with the photovoltaic source is one of the innovative aspects of the proposal. A dual control loop based on the sliding mode control ensures a very fast tracking of irradiation variations. Features of the proposed algorithm are supported by a theoretical analysis and simulations. The technique described in this paper is patent pending
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.
