The Transition from 14V to 42V Automotive Systems
Intertech Corp. announces the
up-coming seminar "The Transition from 14-42 Volt Automotive Systems," The Basics of Motor, Drive and Power Electronics Design for New Automotive Electrical Platforms, will be held April 8-9, 2002, at the Hyatt Rosemont Hotel in Chicago.
This seminar will provide attendees with a comprehensive overview of the opportunities and challenges of 42V systems, beginning with the most significant design changes for starters, alternators and starter-alternators.
Participants will start by learning about both crankshaft and side-mounted starter-alternators, then move along to comparisons of semiconductor technology, power MOSs, IGBTs, Smart Power ICs, rectifiers and analog ICs.
Attendees will also learn about technologies that compete with the battery (a
key part of 42V systems), including the use of supercapacitors with DC-to-DC converters. Discussion of systems, loads and power con-trol architecture will be given, including all aspects of vehicle electrical systems, as well as transient suppres-sion. The pros and cons of rewinding existing auxiliary motors to 42V will be described, as well as the use of a PWM converter — which can allow the use of existing production12V and 24V motors.
The expected introduction timetable for 14/42V systems will be laid out, including early implementation of electromagnetic valves and direct injection. Proposed 42V standards will be thoroughly discussed. Other power electronics issues will also be covered — such as the choice of packaged versus chips-in-modules, thermal aspects and reliability. Finally, other systems beyond 42V will be explored, providing a complete analysis of the transition from 14V to higher voltages.
