On grid solar inverter is an electronic device that converts the direct current generated by solar photovoltaic panels into electric energy close to standard alternating current, so as to be incorporated into the public grid for power supply. In the photovoltaic power generation system, the elect...
Harmonics appear more and more frequently in our daily life. The more frequent to find a high presence of harmonics usually in hospitals, universities, government centers, shopping centers, laboratories, heavy industries, radio, TV, broadcasting, food industry, hotel and casino, highly automated ...
The GS40 series power controllers are designed to proportion electric power to resistive and inductive loads , such as ovens, furnaces, transformers, heat sealers, etc. The controllers consist of power semi-conductors (SCRs), properly-sized heat sinks, trigger circuit. The power controller accept...
Active harmonic filter is a type of electronic device that is used to eliminate harmonic distortions in electrical power systems. Harmonic distortion refers to the presence of unwanted frequency wave in the power system that could lead to issue of increasing heating of equipment, reducing system ...
