无触点记忆继电器在晶体管双稳态触发器中插入磁心元件,可以构成无触点的记忆继电器。一、单磁心晶体管记忆继电器我们看图13。它和常见的自偏压双稳态触发器类似,不同处是射极回路中串入了具有矩形磁滞回线的磁心(W_1、W_2是绕在磁心上的
Contactless Memory Relays Insert a magnetic core element in a transistor bistable flip-flop to form a contactless memory relay. A single core transistor memory relay We see Figure 13. It is similar to the common self-biased bistable flip-flop with the difference that a magnetic core with a rectangular hysteresis loop (W_1, W_2 is wound around the core
