Micro DC-DC Converter Applied to Wireless Access Point

Vicor brick power passenger flight network in commercial airlines

As early as these 10 years, it was confirmed for the first time that the flight network used by passengers in commercial aviation has only become reality now. The early system restricted the use of dual-channels by large, heavy, large jet airlines. Those who rely on satellite technology suffer from the uncertainty of receiving signals. Most of the systems, in addition, are expensive to use.

Airline with wireless Internet access on board and a new source of income. Leading wireless technology, system use proves to be low cost, while at the same time avoiding competition methods requires more heavy airborne equipment. The critical avionics hardware contains two packages, one of which includes the power supply - it is small, low weight (less than 150 pounds), quick installation, and low cost.

Based on the power supply, installation and analysis, the electronics are presented in the cargo hold, only 11.5 inches high and 6.85 inches in weight and only 3 feet deep and 47 pounds. Two 300 volt input Vicor micro DC-DC converters each cpu-powered CPU board Wireless Access Point (WAP). They provide two outputs, 5 volts and 12 volts, 50 to 75 watts of energy.

In the production of WAP is a large volume of material for multiple airlines using wireless network systems. The avionics contractor who chose the Vicor module is lightweight and has a small footprint because of the good history of their modules and Vicor.

characteristic:

Vicor's full-size, small, and micro DC-DC converter modules mark a significant leap in performance and flexibility for similar products. Through advanced power processing, control and packaging technologies, the processing cost per watt of power is reduced while the power density is increased by a factor of three. Low noise zero-current and zero-voltage switching architectures, as well as semiconductor power device packages, reduce low-temperature rise, and increase power density. The high degree of silicon chip integration reduces the number of components by more than two-thirds over the VI-200/VI-J00 modules and increases product reliability.

In addition to the existing standard series of 24V, 48V, 300V, and 375V inputs, full size, small size, and micro size allow customers to set their own product parameters without having to endure a long development period as they would with custom products. The user can freely set different input/output and power combinations, which means that there is no need to be restricted or compromised by the standard products. Log into the CMDS to design your module.

Compact, highly efficient full-size, small and micro converters with wide input range, remote sensing, better output programming and low standby loss. Modules can be paralleled to provide higher power or true fault tolerance. There are five temperatures Specifications (minimum operating temperature -55°C and storage temperature -65°C). Three substrate styles and two pinouts provide the most cost-effective choice. This circuit system is all potted and sealed for harsh environment applications.
