The resources on earth are being plowed by humans day after day. Non-renewable resources are getting less and less every day, and the long-term impact on people's thirst for resources. However, the emergence of new energy gives people a glimmer of hope. In particular, the emergence of renewable resources has given more help to human life and at the same time has given people a new understanding and method of energy use in the future.
LED lights flip clock is the upgrade of flip clock. At the same time, it has both light and time function. In this way, you buy a flip clock, get a light too. Turn on the light to be a lamp when it's dark. Personally, I like this kind of Special Flip Clock, which make my house unique. If there is one thing must to buy for new house, then LED Light Flip Clock must be the first choice.

Renewable energy can be used as a kind of power generation resources, its power generation function has a strong randomness, issued by the instability of electricity, generally can not be used directly, which is a major disadvantage of renewable resources, so the need to use electricity Electronic devices can be converted before they can be used to make full use of renewable resources and achieve greater value.
Renewable energy mainly refers to renewable energy such as solar energy, wind energy, hydropower energy, ocean energy, biomass energy, geothermal energy, fuel cell, etc. as a new green energy, which is never exhausted, pollution-free and not restricted by geographical resources Its advantages are being rapidly promoted and applied. It has also been actively promoted by the United Nations Environmental Protection Organization. Renewable resources will be one of the best energy sources for the future development of mankind.
In the environment where renewable energy is actively promoted by all walks of life in the world, the key technology to solve its use value - power electronics technology has become the most concerned technology. Electronic power technology will be directly related to the development of renewable energy power generation technology.Discharge of renewable energy to change the size of the DC or frequency changes in the AC, the need for power electronic converter to transform the electrical energy. As a result, PCIM Asia's Power Electronics, Smart Sports, Renewable Energy and Energy Management exhibitions bring new impetus to the renewable energy market such as photovoltaic and wind power generation through the latest trends and products introduced through exhibitions and seminars. The trend of energy utilization, revealing the value of renewable resources and how to develop the veil.
A variety of power electronics technology used in renewable energy power generation, including inverters, solar chargers, matrix frequency converters, active filters. Whether photovoltaic panels, wind turbines or other renewable energy sources, even fuel cells need to be converted through power electronic devices to enter the grid. Whether in the monitoring system or energy storage devices, and even grid grid system also must have power electronics control and conversion, we can see the importance of power electronics technology is irreplaceable.
Last year's PCIM show, many exhibitors brought the latest power electronics technology. Such as: Mitsubishi Electric to demonstrate its new MPD series IGBT modules, the new MPD suitable for large motor drives, distributed power generation (such as wind power) and high-power UPS and other occasions, which provide excellent equipment to solve wind power.
Other companies have brought wind power related technology and equipment, Infineon demonstrated its 1200V and 1700V PrimePACK Chopper series for wind power converters, solar inverters and general-purpose inverter . Yingfeng Electronics showcases its use in industrial inverters, inverters, wind turbines and UPS systems. CSRG exhibited IGCTs for 5MW and above wind power converters, large mill drive converters, large ship drive converters, smart grid transmission and complement devices. SEMIKRON controls the new power modules of the SEMIKRON for three-level solar and UPS applications. Rogers Corporation brings Curamik's Al2O3-DBC substrates for use in concentrated photovoltaic cells (CPVs). These devices all reflect the important role of power electronics in the development and use of renewable energy, activate the vitality of renewable resources and provide a strong guarantee for the sustainable development of society.
