IGBT module PWM switching frequency

hi

What is the maximum PWM switching frequency of BSM 50 GB 120 DN2 module?

There's no such quantity. Achievable switching frequency is demanded by acceptable switching losses. A reasonable question could be, what's the maximum switching frequency for a specific bus voltage and output current?

As a ballpark number, I would assume 5 to 10 kHz for "rated" current and 600 - 800V Vdc, higher frequency only with serious derating.

Switching loss is (Eon + Eoff) * PWM_Frequency...then you add your conduction losses, based on duty factor.
