Q13 ACLF option
Function
TopCon power supplies are DC voltage or DC current sources with the
ability to operate at high currents. The utilisation of time-dependent
functions at low frequencies is typical.
There are application cases in which the characteristics of the TopCon
are very appropriate, however the polarity of the output voltage must
change.
A practical example of this aspect is a demagnetising workstation that
subjects the material to be demagnetised to an alternating, decaying
AC field at low frequencies. The ACLF system is intended for this pur-
pose (ACLF = AC Low frequency).
The basic problem
As a DC power supply the TopCon system only provides unipolar volt-
ages at medium powers (at low frequencies). However, there are cases
where the TopCon power supply can only not be used because a bipo-
lar voltage source is required. A normal frequency generator can, how-
ever, as a rule not provide enough power.
The solution
The ACLF system combines a TopCon power supply (or a multi-unit
system, if higher powers are required) with a power inverter.
With this configuration, it is possible to generate and supply to the load
bipolar voltages/currents at low frequencies.
Fig. 56 shows the principle of the ACLF system. The downstream in-
verter makes it possible, e.g., to convert pulsing DC into a bipolar cur-
rent that is then output to the load.
