Established in 1994, Yamar has been developing unique AC and DC-BUS multiplex powerline communication technology and semiconductors to reduce wiring, save weight, cost, and space wherever harness cables are used. Powerlines are typically very noisy due to impulses generated by loads powered from these lines. The DC-BUS technology overcomes it.
Yamar is aiming toward the mass markets such as automotive, working closely with leading car manufacturers to develop optimized solutions for their needs. Other industries discovered Yamar's powerline devices suitable for reducing harness in their applications. Today Yamar has various projects in the fields of Automotive, Aviation, Consumer Electronics, Security, Space and even Toys. Yamar participates in the SCARLETT 7FP European program for second generation Integrated Modular Avionics directed by Thales, Airbus, GE and others, providing its DC BUS powerline communication networks to save harness. Before, Yamar successfully participated in the SPARC European 6FP program directed by Daimler providing redundant CAN BUS powerline communication network between truck and trailer and back lights control without dedicated harness.
The DC BUS Powerline Communication Technology
The DC BUS technology enables network powerline communication of Data, Voice, Music and Video signals by digital means over Direct Current (DC) battery power-line like those used in every vehicle. Yamar succeeded to deploy advanced digital communication techniques tailored to overcome hostile and noisy environment such as on vehicle battery lines in a small size silicon device. Customers integrate the devices into modules utilizing their own application (e.g. within body and power train modules for in-vehicle multiplex communication networks). Same powerline can be used for multiple independent networks by using different carrier frequencies. Prototypes are successfully operational in vehicles.
