Switching Frequencies
The power supply has four converters with four different switching frequencies included.
One is nearly constant. The others are input voltage and load dependent.
Switching frequency 1
80kHz
PFC converter, nearly constant
Switching frequency 2
80kHz to 95kHz
Main converter, input and output voltage dependent
