In the plating industry application, normally, there are two types of rectifier, which is:

1, Silicon controlled rectifier.
2, High frequency power supply.
While, what is the different between for the 2, sometimes it will cause us confused to choose them.
Here we use a table sheet to find out what exactly difference for them.

For easy to distinguish, we choose same power: 1000A 12V type rectifier. From this, I think you will know which one is what you want.
