6 FAQs about [Industrial energy storage optocoupler]
Why are optocouplers used as isolation devices?
As isolation devices, optocouplers were invented in 1963 at IBM and have come a long way from its origin as a simple light bulb coupled with a photo resistor. Maturing technology of solid state light sources i.e. the LED, have lead to a miniaturization of the optocoupler and its wide usage in industry as an isolation device.
What are optocouplers used for?
Optocouplers typically: For the reasons listed above, optocouplers are very common in digital or microelectronic devices that require fast switching and utilize low voltage transmissions. The following video explains the basic construction of optocouplers, their primary uses, and their similarity to relays.
What is the operating temperature range of an optocoupler?
Furthermore, the operating temperature range in the datasheet of the optocoupler is between -55°C and 100°C. In a similar way to the voltage selection, one of the temperature conditions is chosen lower than the maximum value from the operating temperature range i.e., 90°C.
How to increase the lifetime of optocouplers?
Given the reliability data provided and the presented equations, we could suggest some design guidelines to increase the lifetime of optocouplers: Decrease the effective operating time of the optocoupler. Adjust the duty cycle of the LED, in order to keep the average current low.
How a solid state light source is used in a optocoupler?
Maturing technology of solid state light sources i.e. the LED, have lead to a miniaturization of the optocoupler and its wide usage in industry as an isolation device. Today most typical optocouplers consist of an LED that is optically coupled to a phototransistor, photo-Darlington or photo-Triac.
How do you calculate the lifetime of an optocoupler?
The parameter values of the proposed degradation curve model are calculated by applying the Arrhenius model and Weibull distribution, and the lifetime of the optocoupler is estimated by using the proposed degradation curve model.
