      Lighting industry continued to take the heat, in addition to LED luminous efficiency improvement and cost factors in the decline
In addition, the main thrust is that the governments of energy-saving environmental protection industry, the increasing emphasis on new energy and large
Force support. Both the 2009 World Climate Conference in Copenhagen, concluded, or the current world in many countries
Home an important measure to address the financial crisis, support the development of new energy has always been of decisive importance to
Bit.

      All indications are that the new energy will be a low carbon economy based on modern technological revolution. Can
To anticipate 2010 will be the new energy development around the year. Future new energy industry value chain
Collection will focus on new energy and new energy, more efficient collection and open up new applications of new energy sources will
For semiconductor manufacturers to develop new value growth. Such as LED lighting, solar / wind power, electricity
Moving cars and more new applications.

      Electronic Components and Technology Network order to explore new energy sources by 2010 a new highlight on the electronic components
And new applications, solar / wind power and other fields of technological progress and market demand for electricity caused by
Changes in demand for sub-devices and the latest challenges.

 

      Wind power: 2010 New Opportunities / New Challenges

      The various types of renewable energy, from the current technical maturity and feasibility of the construction point of view, the wind
Can be most competitive. In the long run, the global wind energy industry is quite optimistic about the prospects, governments are not
Off the introduction of favorable policies to encourage renewable energy development, the industry, a huge market opportunity.
Deutsche Bank recently released a research report, the global wind power development is the rapidly expands
Period, wind energy industry will maintain an annual growth rate of 20%, 2015, the industry output will increase to
5 times the current level. Such a huge demand and market for semiconductor companies to provide new opportunities
And challenges.

      Because wind energy is a very unstable source of energy, wind turbine output voltage, frequency and power
Very unstable, so do not directly deal with supply network. From wind power to the Grid
Process, rectifier, inverter, thyristor, protection devices, transformers and other devices to play the heavy
To the role.

      One can achieve with the existing national power grid is usually large-scale wind farms mainly to
The following components: wind turbines, rectifiers, inverters, controllers, thyristors, with
Step devices, lightning protection devices, transformers, connectors and other control systems.

      Rectifier which is used to wind turbines convert alternating current into direct current sent to Feel
Can reduce energy loss during transmission. Near the grid side rectifier inverter off and then
To the DC power into a grid using the sine wave, and then through the thyristor and the synchronizer to ensure
Synchronized with the grid generated by AC and the AC sine wave, and the electricity grid.

      Usually by the IGBT inverter module, freewheeling diodes, IGBT gate driver, driver protection
Protection, filter capacitors, choke coils, radiators, isolators and MCU composition. Wind Turbine Efficiency
And directly related to the efficiency of the inverter, and then in turn depends on the energy efficiency of components, so the domestic electricity
Sub-components company in the inverter market, there is a huge opportunity. In addition, wind power application requirements to contractors
Current in amperes by the thousands and thousands of high voltage high power IGBT devices or modules, and they will be required
Must have high reliability, which for the production of high reliability, high-power devices provide a new
Energy services business.

      In order to absorb more energy, hub height and with increasing impeller diameter, also increased the relative
The risk of being struck by lightning, lightning into the nature of the wind turbine generator to run the most harmful
A disaster. Lightning can cause the release of enormous energy wind turbine blade damage, generators
Insulation breakdown, burning and other control components. Therefore, wind turbine lightning protection solution seems very
Important, lightning protection devices against over-voltage shock is generally the gas discharge tube (GDT), thyristors, TVS II
Diode or metal oxide varistors (MOV), and the impact of anti-recoverable PolySwitch overcurrent device
Piece or one-time fuses. 2009 Electronic Components Technology Network launched in circuit protection seminar brought together
The industry's best circuit protection enterprises, while providing a complete set of circuit protection solutions.

      Between the inverter and power in general need to increase the transformer, because the general high voltage power grid
Tens of thousands of volts, such a high voltage inverter can not be done, requiring a large step-up transformer,
Large Transformer domestic enterprises started earlier, technology and price advantages are obvious, such as Tianwei change and other countries
Within the enterprise.

      Reduce the cost of birth of the solar energy industry expansion

      As a new energy to another big market for solar applications, according to 2010 estimates TRI
Market demand for solar power generation in China will reach 620 million U.S. dollars, up 138.5% of the annual growth rate can also see
Out of its development potential.

      Hard to promote a broad market makers reduce the cost of solar power, the most simple way
Method is to increase the conversion efficiency of solar cells.

      Solar photovoltaic conversion efficiency but to achieve the majority of commercial production does not exceed
20%, although with much room for improvement, but was limited by restrictions on the basis of material progress of the upgrade is
Slow. Look at the core of the application of AC power generation components: solar panels, solar charge control
Devices, batteries and inverters, semiconductor manufacturers the opportunity to focus on charging and inverter link.

      Since the input of solar energy photovoltaic power generation system unstable, so in general need to configure
Battery system to work. Solar cells produce direct current into the battery before storage, to
A certain threshold in order to supply lighting loads. A direct impact on the characteristics of the battery system efficiency,
Reliability and price. The choice of battery capacity generally follow the following principles: First, to full
Adequate lighting at night under the premise of the solar modules during the day and store the energy as much as possible down at the same time
Also able to store a predetermined consecutive rainy days night lighting needs of the power.

      In the solar system, the inverter into alternating current to direct current, when the lighting load for the DC
Without having to use (such as LED lighting), there are already solar-powered LED lighting system directly, as opposed
Believe this trend will be more applications in the future. The lighting load must be made for the exchange of load
Use. Taking into account the low conversion efficiency of solar photovoltaic, which underscores the important conversion efficiency inverter
To. Solar inverter power electronics selection for minimum loss of the inverter and the highest
Efficiency is critical to the solar inverter applications, the insulated gate bipolar transistor (IGBT) can
Provide more than the other benefits of power components, including high current carrying capacity to voltage instead of current
Control, and can reverse parallel diode and IGBT with, how to correct for the solar inverter
Applications selected IGBT, is an engineer in the design of the inverter to improve the conversion efficiency of challenges.

      In addition, most stand-alone solar power equipment in remote and harsh working environment, which requires
Inverter can be used in harsh environment and less work to maintain long-term stability under the conditions, many
Inverter also added a short circuit protection, undervoltage protection, overcurrent, reverse polarity protection and lightning
Protection.

      Company expects 2012 global inverter for solar energy systems from 2008 shipments
A growth of 723,329 during 950 million. Broad application of solar system need to use more
Battery and inverter, which is engaged in power supply design and component manufacturers to bring great opportunity.
