STMicroelectronics to Showcase its Advanced Solutions at PV Japan 2011
/PRNewswire/ -- STMicroelectronics (NYSE: STM), a far-reaching semiconductor leader serving customers across the spectrum of electronics applications, and a leading provider of solutions for photovoltaic systems, will showcase its biting-edge solutions at PV Japan 2011 under the theme "Smart Semiconductors from the Sun to the Grid." With the increasing importance of renewable energy, ST is contributing to the deployment of power-era systems optimizing the use of solar energy with highly efficient solutions that combine advanced technologies and system know-how.Outstanding solutions to be highlighted at the ST booth
ST will showcase a new concept device, called a "smart junction box" that maximizes the power era of photovoltaic systems. Conventional junction boxes are equipped only with bypass diodes, while DC-DC converters and 32-bit microcontrollers or DSPs proficient of adding intelligence and control to the system are relegated to upstream power conditioners. In these traditional systems, a single power conditioner optimizes the power generated by multiple solar panels. In such systems, if the power generated by a unwed panel drops, the output power of other panels also drop. Under ST's new concept, microcontrollers, DC-DC converters and communication ICs are distributed to each juncture box of the photovoltaic system to maximize power generation as well as to enable remote monitoring and control. ST's smart junction box allows extremity power-point tracking (MPPT) to be separately set for each panel so that a drop in power generation from one solar panel has not enough effect on overall system power generation. Additionally, the built-in 32-bit microcontroller and PLC SoCs enable users to assess the eminence of each panel and control them in real-time. The efficiency of ST's smart junction box allows quick recovery of the primary investment, while reducing maintenance and management costs and improving the overall safety of the photovoltaic systems into which it is installed. ST will also suggest its microinverter concept for plug-in PV modules, which can further accelerate the adoption of small-scale distribution-type photovoltaic systems. Normally, deploying photovoltaic systems to households is precious. With ST's new concept, a complete small-scale photovoltaic system can be realized by installing one microinverter per solar panel, enabling consumers to question begin photovoltaic generation.This microinverter is equipped with ST's power MOSFETs, ARM Cortex-M3-based 32-bit microcontroller, and SiC diode, which together surrender better than 95% power efficiency.
