Application of the Semiconductor Breaker/Relay on vehicle circuits
In this paper, the modified Semiconductor Breaker/Relay (SBR) and related control modules, and some new methods to solve the problems of vehicle fire, battery service life and engine cold start emission have been presented. By theoretical and experimental analysis on applying the modified SBR etc, vehicle fire relating to circuit system may be avoided because of the fast and accurate control, battery service life can be extended because of the cyclic charging effect, and engine cold start emissions can be decreased because of the lower power consumption and the faster reaction of the catalytic converter during a cold start. Further study for the detailed numerical values still needs to do.
This paper presents the design, prototype realization and measurement results of the liquid crystal bias voltage-tunable ::: microwave band stop filter. A possible use of liquid crystals for tunable band stop filters was shown.
