The first commercial flight of the 787 Dreamliner
Innovation and Electrical Power Conversion

On Wednesday October 26th, the new 787 Dreamliner made its first commercial flight from Tokyo to Hong Kong, with 252 passengers on board, some of whom had paid thousands of dollars for the privilege.

Boeing has selected leading electrical power conversion technology from Thales to efficiently power the vast array of consumer systems onboard the 787 with the least environmental impact. These systems, both conventional and new, include Thales IFE, as well as electrical environmental control systems and the electrical brake system.

Thales's lightweight system offers a reliable, innovative and optimised solution for power at a range of voltage levels to meet the 787's significant electrical demand and related need for AC/DC power conversions
Thales's power conversion system has achieved a very high power density benchmark, further contributing to reductions in both weight and volume onboard the 787. The new-generation power conversion system includes an innovative transformer and rectifier solution that supports the 787 high-voltage DC network.

Boeing chose Thales's lithium-ion battery technology, which provides higher reliability and improved maintenance compared to traditional solutions, for the 787 low-voltage DC emergency back-up subsystem. This is a first in civil aviation, with Thales as prime contractor in association with Securaplane of the United States and GS Yuasa of Japan.

The flight to Hong Kong was organised especially to coincide with the launch of the Dreamliner. The first regular international flights of the 787 will be from Tokyo to Beijing, starting in December, followed by Tokyo-Frankfurt from January onwards. The first domestic flight for the aircraft is scheduled to be on the 1st November from Tokyo to Okayama (west) and Tokyo to Horishima (west).
