One touch ultra usually USES the hige role will work frequency power transformation for another frequency of electric control device. The main circuit of frequency converter substantially can be divided into two classes: the voltage type of dc voltage source is will transform into exchange converter, dc circuit filter is capacitance, Current model is current source of dc transformation for communication, the dc converter circuit filter is the inductance. PWM Width Modulation is English points (Pulse Width Modulation) abbreviations, according to certain rule change Pulse list of Pulse Width to adjust output and waveform a tone contours way. PAM is English Amplitude Modulation points (Pulse Amplitude Modulation) abbreviations, is according to certain rule change Pulse list of Pulse Amplitude, to adjust the output value and waveform of a kind of Modulation mode.

Diesel Generator is a small power generation equipment, means with diesel oil and other as fuel, carbon steel pipe with diesel generator for prime mover generating power machinery. Full set group generally by diesel engine, generator, control box, RanYouXiang, startup and control with storage battery, protection device, emergency cabinets etc. Parts. Overall can fixed in basis, positioning use, yi ke installed in the trailer for mobile use.

Gasoline Generators sets of a continuous operation of generating equipment, if continuous running more than 12h, its output power will be lower than power rating approximately 90%. Although diesel generating sets of power is relatively lower, but because of its small volume, flexible, light and necessary is complete, easy operation and maintenance, so are widely used in mines, railway, field site, road maintenance, and factories and enterprises, hospital departments, such as backup power supply or temporary power supply.

Generator, is the mechanical energy into electricity. The air-cooled diesel generators Usually consists of turbine, turbine or internal combustion engine drive. Electricity is the most modern society is one of main source of energy. Generator in industrial and agricultural production, defense, science and technology and daily life have been widely used. Generator is divided into dc generators and alternator two kinds big. The latter can be divided into synchronous generators and induction generator two kinds. Modern power stations in the most commonly used is synchronous generators.

Inverter is scheduled for winding loss due to the heat produced by oxen, when using air cold when need through insulating layer appearance, consequently conductor air flow away have higher temperature, core temperature difference is big also, cause winding bar and core produces thermal stress caused by thermal deformation, thereby affecting the insulation life and endanger the motor running safety. International generally used internal water-cooled methods to improve the performance of large generator, but in the water leakage, plugging cold exist and corrosion cause accidents weaknesses, but also the blood glucose test strips essence of supporting complex water treatment equipment and drive system. The results are based on the independent innovation of CLSC evaporativecooling system technology, development and promotion of the design calculation technology and unique system structure. The frequency inverter development of stator winding the world with new cooling technology of large-scale hydraulic generator, the cooling technology leading international motor, the overall performance in international front row.

The same calculation methodology applies to this index as the solar module index: it is based on the purchase price for a inverter. The main difference in methodology between this index and the solar module index is that all global inverter prices are aggregated into a single index. Those aggregated products are then translated from the local currency into either US dollars or European euros.
