Under the motto "Delivering tomorrow's technology today", Rutronik makes its appearance at the Embedded World Exhibition as a supplier of innovative components and complete solutions. Advanced application examples from the medical, lighting, automotive, wireless and automation sectors as well as inverted rectifiers, metering solutions, industrial PCs and TFTs show Rutronik's comprehensive product portfolio.
The overall focus is on the subject energy efficiency and renewable energies with components and applications for smart metering, environmentally sound lighting concepts with LED technology as well as electric and hybrid drives. The alternative energies sector is covered by the subsidiary Rusol, specialist for photovoltaic solutions. Here, Rutronik supplies the necessary components, especially inverted rectifiers required in PV systems. This is completed by comprehensive value-added services, such as design-in support and technical advice by product and application specialists, which are available to customers in all countries throughout Europe.
STMicroelectronics has developed a new system for grid-connected PV applications to achieve improvements in design, technology and manufacturing. On Rutronik’s Booth, you will be able to see the 3 kW PV system which consists of a high frequency isolated input power section performing DC/DC conversion and an inverter section capable of delivering sinusoidal current at 50Hz to the Grid. The system operates with input voltages in the range of 200 V to 400 V and is tied to the grid at 230Vrms, 50Hz, through an LCL filter. Other characteristics of the proposed converter are integration level, decoupled control of active and reactive power. Further, a fully digital control, including power management for grid-connected operation and MPPT algorithm, has been implemented on a STM32.
