Invert Mini Electronic

Electronic Components Pilot Stepped Into A New Energy Era Appliances

E The rapid development of technology adds to human life, bright colors, but with the industrialization and urbanization deepened, electronic technology has also cast a shadow over the world.

Electricity from a number of other

Energy , Most of which are non-renewable energy resources, excessive consumption of energy affect sustainable development of the future of human society. Therefore, environmental

Energy , In particular, issues of electronic products, energy efficient one as a hot topic right now. Careful observation reveals that energy

Environmental protection Of integrated circuits often focus on, neglecting the role of electronic components. Electronic components as the basis of electronic information products, has been quietly supporting the development of electronic information industry. U-disk from the mini to the aerospace, electronic components everywhere. Terms of use or system cost in terms of the number of electronic components more than the integrated circuit, electronic components, therefore can not do without energy-saving topics.

China is the world’s

Home Appliances Production base, annual production value of 6,000 billion appliance industry, and the Chinese home appliance products, power consumption has more than 15% of China’s total power consumption. Therefore, energy saving appliances bear the brunt of energy into the object, in particular domestic Big Three? Air conditioning, TV,

Washing machine Energy conservation is frequently challenge the limits.

Air conditioning: power devices, both motor

To go home appliances shopping mall look around

Inverter air conditioner Accounted for most of the counter, you can see the energy-saving inverter air conditioner that has advantages as well as to create a living environment has been more acceptance, and government departments will list energy-saving inverter air conditioner into the lead role, but also created a virtually air-conditioning for the frequency good reputation.

Power devices and energy-efficient air conditioning compressor motor is the two key components, Mitsubishi Electric mastered the core technology of the two air conditioning accounts for the success frequency air-conditioning,

Refrigerator And the washing machine market share of 60%. The industry to grasp a lot of power semiconductor technology company, but to master the power semiconductors and motor companies are very few. Mitsubishi Electric Corporation Division of the Minister of Environment to promote leech Tiandao Fu introduced in the future the company plans to use SiC (silicon carbide) module to further improve inverter efficiency. If all the existing products can be switched into silicon carbide products will substantially reduce energy consumption. According to Mitsubishi Electric has done a conversion, if the 2015 date, all semiconductor switch silicon carbide semiconductors, energy savings could power the equivalent of 2 million population. Leech Tiandao Fu said, the current progress of SiC has completed the development of empirical test. He hopes the development of this technology by 2010 to the practical level.

First inverter air conditioner compressor motor for the AC motor, after the technology to use brushless DC motors. Mitsubishi Electric has introduced the industry’s most efficient known as the “keel motor”, its original core is like the compressor motor keel keel can still start on the commencement of the stator core high-density land around after the fold the copper, significantly reduce the size of the motor, and realized the close of routing and volume of the narrow, greatly improved the efficiency of the motor.

Washing machine: direct drive permanent magnet synchronous motor show their skills

Relative to the air-conditioning, washing machine’s energy is more complex, involving the power consumption, water consumption indices. The home appliance market characteristics for the average consumer, but also take into account the price, in order to achieve low-cost energy-efficient performance.

“Traditionally, home appliances such as washing machines are used in the motor inductance machine, to fixed speed operation, and only using mechanical transmission, or work cycle is not precise, and less efficient regulation technology. If speed permanent way to replace these motors can be reduced by up to 60% of energy waste. “International Rectifier (IR) PaulRolls senior vice president of global sales of the current technical situation of electrical household appliances, said,” The problem is the electronic control unit design complexity, including digital, analog and power stage.
