The item under about ac solid state relay circuit has gotten lots of interest, a good deal greater than any other on our web site. We believe it really is for the reason that it pulls no punches. Yet, though it is an important problem, it is not all doom and gloom, there is a further point of view that some obtain fairly unorthodox, but workable.
This product short article has verified to become extremely helpful to our readers and so they come back regularly to maintain abreast on the most current developments. Though ac solid state relay circuit remains an important topic, it really is generally an added bonus when you is usually enlightened, as well as amused by being shown the other side in the concern. Some factors will not be always what they appear.Read on for far more insight.”

Prithwiraj B asked what are the switching ics that will be controlled by dc 5V and will operate ac 230V, 50 Hz.?
The IC I want is the one where in the output side it will short the pins when it will receive a 5V DC voltage. In the output there will be ac 50 Hz 230V power supply.
And got the following answer:
There are no ICs that can have 230V connected directly. All will use some sort of interface, a driver. One simple method is to use the logic signal from the IC to operate a relay or contactor. Even so this is not straight forward. There usually needs to be a driver for the relay too. The relay may be replaced with other devices like a triac or SCR or solid state relay. They each have their own driving requirements. ANother important point is isolation. You don't want the mains connected to your logic device. It is isolated by a relay, and by the driver circuit (which is internal in a solid state relay). The relay will have contacts rated for 230V AC at some specified current. It will have a coil that is operated by a DC voltage and current. This usually will not match the IC itself (which may be 0 or 5V @ a few mA output. Additional transistors and a relay power supply provide the drive for the relay. See the first link, but a single transistor may not suffice as the current gain is insufficient. Instead, use a "logic level N channel power mosfet" to drive the relay. Its current rating can be 1-10A The most straight forward device for your needs is a solid state relay, as the driver is built in. It switches 230V AC, up to approximately 10A. The input is isolated from the output, and may operate when >3V and negligible current. It does not work well with inductor loads like a transformer or motor. Fast rates of current change cause voltage spikes that can turn the device on or off unexpectedly. A snubber is used to control this. See the second link.
