Single-phase full-wave controlled rectifier circuit
Figure 2-9 Single-phase full-wave controlled rectifier circuit and waveforms Single-phase full-wave and single-phase full-control bridges are basically the same from the DC output or from the AC input.
The difference between the two:
(1) The structure of the transformer in single-phase full-wave is more complicated, and the winding and iron core consume more copper, iron and other materials;
(2) Only two thyristors are used for single-phase full-wave, which is less than two single-phase full-control bridges. Correspondingly, there are two fewer gate drive circuits; however, the maximum voltage that the thyristor is subjected to is a single-phase full-control bridge. 2 times;
(3) The single-phase full-wave conduction circuit contains only one thyristor, one less than the single-phase bridge, so the tube pressure drop is also less. Considering the above (2) and (3), the single-phase full-wave circuit is beneficial. Application where low output voltage is used.
Outdoor Led Display screens for rental-- Die casting cabinet
LED technology is the latest and the best in terms of the audio visual technologies out there and it is still evolving. There is a strong emphasis in making LED display screens energy efficient, cost efficient and light weight apart from other quality requirements. Hence,Stage LED screen cabinets are also now expected to be lighter in weight. This need has resulted into the gradual shift from the iron cabinet, aluminum cabinet, to the cast-aluminum and die cast aluminum as the weight of the cabinet is lighter. Cast aluminum and die cast-aluminum cabinets are the latest of the cabinets used for LED casing.
The cast aluminum and die cast-aluminum cabinets have high strength and high tenacity. They are highly efficient, provide excellent heat dissipation, energy conservation and environmental protection. Because of their outdoor usage, Rentel led display cabinet is made as a waterproof cabinet of leasing cast aluminum. They are lightweight and ultrathin. They are quite flexible for easy packaging and lifting. They have a high refresh rate, high grayscale and are widely applied to the stage renting. They are easy and simple to install and thus help you save on precious time and man power as one-person can easily do the insallation. Cabinet splicing and wiring connection is fast and reliable. Not only great in looks dept. it can be easily dismantled. Casting Aluminum and die Casting Aluminum Cabinet also have better deformation resistance property.
