The T6
APD
must be pre-charged via a appropriate circuit. This is to be carried
out, for example, passively with a minimum precharging resistance of 3
Ω
or
actively by means of power electronics. When dimensioning the permissible
current of the used DC fuse must be observed. This can lead to a larger mini-
mum precharging resistance.
