42V PWM Conversion & Control Technologies and E/EDS Architecture 2001-01-0725
The automotive industry is transitioning from the present 14V electrical system to a 42V system. This voltage evolution is due to the number of new systems (safety, fuel economy and customer convenience) being developed which require increased electrical power that a 14V system cannot deliver. During this transition, it will be necessary to control 14V subsystems in a 42V architecture. This paper presents 42V PWM (Pulse Width Modulation) voltage conversion and control technologies as a solution to control these 14V subsystems.
