Optocoupler Device CTR and Circuit CTR Explained

When you already heard about Optocoupler devices, you may be heard also about CTR. CTR stands for current transfer ratio. In bipolar junction transistor this is the so called current gain or simply beta. It is the ratio of the collector to forward current of an Optocoupler. In circuit design involving optocoupler, you may be dealing with the device CTR

Opto Coupler CTR Explanation

Opto coupler CTR explanation is not well elaborated by other authors and before I was also having hard time of understanding what is it. Current transfer ratio or commonly known as CTR is the ratio of the collector current to the forward current of an optocoupler. It is synonymous to a current gain of a bipolar junction transistor. If this is the first

How Optocoupler Works

What is an Optocoupler? How Optocoupler works? These are just some of the questions I have before knowing this device. Opto coupler or opto isolator or photo coupler is an electronic device (a semiconductor) which is commonly used for signal isolation such as the primary and the secondary of a switching power supply. Its input circuit is a light source which is commonly a light
