其关键参数之一即为电流传输比(Current Transfer Ratio,CTR),它反映了光耦输入电流和输出电流之间的关系。CTR的值决定了光耦的性能,影响着电路的效率和可靠性。在设计电路时,工程师需要根据具体需求选择合适CTR的光耦,以确保电路的正常运行和性能优化。 'Current Transfer'在电化学中的表现...
Current Transfer Ratio(CTR) is a ratio of the current to the output collector input forward current and is represented in a percentage. CTR is mainly characterized in analog opto-emulator or optocoupler devices. The input forward current (IF) is the current going into the di...
電流傳輸比(Current Transfer Ratio , CTR)的定義為輸出電流和輸入電流的比值(IC/IF∗100%),其測量電路如圖1所示,其 CTR 值可以視為光耦的放大倍率,當 CTR=200%時,所指的是IF=5mA 時,IC=10mA。可是在IF=10mA 時,IC是否一定為 20mA?答案是否定的,因為此倍率並非唯一定值,除了元件本身的特性之外,也受到...
The current transfer ratio (CTR) refers to the ratio of the collector current at the output side Ic to the input current passed to the LED at the input side IF expressed as a percentage. It is defined by the following formula. CTR=(IC/IF)×100 (%) As is the case with hFE for tra...
