Controller structure
TopCon power supplies have the following controller structures:
Parallel arrangement for voltage controllers

and current con-
trollers

Intermediate circuit compensation
An intermediate circuit voltage correction is connected downstream of
the controller. This feed-forward path
-3-
is intended to primarily com-
pensate for the mains fluctuations and in particular the residual ripple.
The ripple is at:
300Hz on 3x400V/50Hz systems
360Hz on 3x480V/60Hz systems
2.2.4.
Principle of the scope of operation/authorisation concept
TopCon power supplies have numerous functions.
The actual scope of operation available is dependent upon:
The authorisation level (user level)
The functions enabled (options)
During this process all interfaces are used to set the necessary parame-
ters and, if necessary, to transfer additional data to the TopCon power
supply.
After the parameters for the power supply have been set to a specific
function, the device undertakes its function autonomously, possibly also
without interaction with the interfaces.
Of course an interface can request information or data from the TopCon
power supply in the mean time. The power supply returns the infor-
mation requested, ho
wever not as a “real-time” function.
