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 
100kHz 
Resonant converter, nearly constant 
Switching frequency 2 
110kHz to 500kHz 
Boost converter, input voltage and load dependent 
Switching frequency 3 
73kHz to 114kHz 
PFC converter, input voltage and load dependent 
Switching frequency 4 
35kHz to 45kHz 
Aux. converter, input voltage and load dependent
