Design and Research of Vehicle Circuit Semiconductor Protection System 2007-01-3702

On the basis of the author's recent research on vehicle circuit protection, a Semiconductor Breaker & Relay (SBR) and a Semiconductor Protection and Control System (SPCS) of vehicle electrical components etc. have been developed. The circuit structure and function of SBR and SPCS etc. were analyzed and explained in detail. By replacing the conventional fuse, circuit breaker, and/or relay, SBRs and their different combinations constitute the SPCS. SPCS could protect circuits and electrical components from over-current, over-voltage, and battery reversing, prevent vehicle fire caused by short circuit, and extend battery's service life by over-discharging and supplemental charging control.
