UPS failure

As shown in the figure, the POWERWARE 9150 UPS is malfunctioning. The cause of the fault is that the UPS does not output any voltage; the rectifier, on the other hand, outputs a voltage of 800V. There is no voltage output from the UPS (on the inverter side). Tests show that the IGBT is functioning properly (with a forward conduction voltage of around 0.4V and no conduction in reverse direction). During startup, there is an instantaneous voltage of about 90V on the inverter side, after which the system shuts down due to an alarm. Please suggest solutions or an analysis of the cause of this fault.
