Alternator regulator increases efficiency of automotive generators
A basic hardware system that can be used in all designs is ideal here because it can be adjusted in line with the specific customer system by means of software.
Up until now, no suitably sophisticated hardware has been available that enables generators in commercial vehicles, agricultural and construction machinery as well as other vehicles with internal 24-V on-board electrical systems to be operated at maximum efficiency. To address this, EBV Elektronik collaborated with key customers and STMicroelectronics to develop the vTARIC generator regulator.
With vTARIC alternator manufacturers now have a universal design for regulating generators independent of the individual requirements of a single OEM (vehicle manufacturer). This means that it is now possible to cover the requirements of all vehicle manufacturers with one single hardware solution – a first in the industry.
The basic idea behind vTARIC was to offer as many degrees of freedom as possible in order to enable a highly efficient system design on the one hand and to implement the necessary control algorithms on the other.
When EBV Elektronik presented the vTARIC concept two years ago, various customers – including some with whom the company had not even discussed the chip – provided valuable inputs. The design team successfully realised most of their requests to create a highly universal component. In partnership with STMicroelectronics, EBV is currently developing a product family that will soon result in four different components: one 12-V and one 24-V version of vTARIC, each with and without a LIN interface.
