hello everyone,
i was studying power electronics, i saw methods on book to design control circuit for converters. but there is also ready entegre controllers for converters.
in which situation, will i need to design new control circuit? and in which situations i will use ready controller entegre?
thanks a lot
You should use an integrated controller whenever possible, because it will save you many headaches while providing many features for a reasonable price. If there is already a product on the market to do what you desire, it is almost always a better idea to purchase it than to build it yourself (unless of course, you are practicing for educational purposes).
This website has many integrated power controllers and regulators, known for their high quality.
You generally need to design a new control circuit if:
a) You are trying to make things even cheaper than an integrated solution can provide (it is occasionally possible to make things cheaper using discrete components).
b) You are trying to implement complex or optimal power control, such as for DC/AC conversion, grid-tie inversion, motor control, or peak power point tracking.
c) You are working with extremely high power levels, and need to implement numerous safety features.
d) You are trying to implement features that are not included in any integrated controllers.
As a final note, when you can't find any integrated controllers which implement the feature you desire, it is often possible still to use an integrated controller—and build a peripheral circuit which implements the feature.
Hope this helps!
