摘　　要：提出了一种新型的双稳态过温保护电路及其雪崩式工作模式。从理论上对雪崩式状态转变及滞回的产生机理作了深入的分析。与传统过温保护电路相比,该工作模式使转换速度提高了3倍以上,同时由于双稳态系统固有的稳定性,电路的稳定性也得到一定的提高。A new type of bi-stable thermal protection circuit and its avalanche operational mode are presented. We focuses on the theoretical analysis of avalanche state transition, as well as on the mechanism of hysteresis. Compared with the conventional thermal protection circuit, a three-fold transition speed from one state to another is achieved, and the stability of this circuit has also been improved due to the intrinsic stability of hi-stable system.

关 键 词：双稳态 过温保护电路 滞回
