Across multiple electronic
applications, the world’s leading supplier of semiconductor and integrated circuit manufacturer
in Techno-Frontier 2011 (2011 Japanese electronic, mechanical parts and materials, Expo) show to the audience on an advanced power system solutions.
These solutions integrate the
latest technology, STMicroelectronics and unique knowledge of the system for
equipment manufacturers to achieve energy-efficient power conversion and power
supply may also contribute to conservation-oriented society, so that the
limited resources to achieve greater efficiency.
STMicroelectronics, the main
solutions on display.
In the solar power generation, STMicroelectronics demonstrated SPV1020 chip,
this DC – DC converter built-in maximum power point tracking algorithm (MPPT),
with power optimization and conversion of double feature, which allows each
chop separate MPPT solar cells set to maximize the output power of each chop
battery. STMicroelectronics will demonstrate SPV1001 cooled bypass switch
function, the integration of low-power MOSFET switch and precision control, and
thus each costing more solar energy can be output, so SPV1001 bypass diode has
the same function. In addition, ST will introduce micro-inverter solution that
allows system vendors to optimize the output of each chop, batteries, to
STMicroelectronics also demonstrates SPV1040 mobile device charger chip for
mobile devices, solar batteries. And control of solar cells produce electricity
more than the ordinary products of different, SPV1040 (can enhance the power
generated by solar cells each chop) is a significant product; this product is
equipped with MPPT function, to optimize the output of solar panels, to ensure
produce the largest solar power. STMicroelectronics using a charger with solar
panels to charge their cell phones to demonstrate SPV1040 the product works.
STMicroelectronics demonstrated STBC21 portable charger chip, when installed on
portable electric equipment within the charger or the device itself, the chip can
fully control the battery charging process. STBC21 can improve the energy
efficiency of the charger, excellent battery protection features to precisely
control the charging time, the status indicator, charge current and voltage.
STMicroelectronics also on display with easy to use portable travel charger
solution. STMicroelectronics use STBC21 presentation tools and the remaining
capacity detection chip, USB detection chips and solar cells to the audience a
live demonstration of these solutions.
STMicroelectronics also demonstrates STC3100 battery remaining capacity
detection chip. In smart phones, tablet PCs and digital camera, STC3100 and
computing devices capable of detecting the remaining battery power.
Smart Grid solutions
In power communications, smart meters are essential components of the smart
grid, STMicroelectronics show home smart metering solutions. STMicroelectronics
demonstrate support for smart meters and meter reading of power line
communication (PLC) charging system. This application demonstrates use of a
power line communication system with ST7580-chip (SoC), STPM series power
measurement chip and the STM32 ARM ® Cortex-M3 ™ 32-bit microcontroller
evaluation board. ST also introduced for the collection of information for each
meter of highly integrated data acquisition system solutions (power data
Through this exhibition, the audience also learned about the integration of
STMicroelectronics’ high-performance motor control circuits required for all
digital, analog and power measurement circuit dSPIN ™ (digital SPIN)
system-on-chip and experience a new energy-efficient LED lighting solutions.
