Green power system has two meanings

Green power system has two meanings:

 

first, a significant saving, which means that the savings capacity, and power generation is an important reason for environmental pollution, so the saving can reduce environmental pollution;

 

second of these power supplies can not be ( or less) on the grid, pollution, the International Electrotechnical Commission (IEC) which developed a series of standards such as IEC555, IEC917, IECl000 and so on.

 

In fact, many power electronic energy-saving equipment, often become the source of power: the power grid into a serious high-order harmonic current, and the decline in the total power factor, so that the peak grid voltage coupling many glitches, and even chipping and distortion .

 

The late 20th century, a variety of active filter and the birth of active compensation scheme, with a variety of power factor correction methods. The green for the 2l century, mass production of various switching power supply products laid the foundation.

 

Modern power electronics technology is the switching power supply technology development. With the new power electronic devices and for higher switching frequency of the circuit topology of the emerging, modern power technology will be driven by the practical needs of rapid development.
