PWM switched Inverter - main components I have to change

[mido46]

pwm inverter losses

Hi,
I'm doing a very complex internship and I realy want your help in designing a 2 phase, sinusoidal PWM inverter , 550V , 130 Amp., Iripple=30 Amp., IGBT model no. is (FGL40N120AND), F sw.= 40 kHz, Driver model(UCC37322), Output filter (L= 300 uH, C= 940 nF), load: linear motor.
the designing of this system in based on a hard switched IGBT and I have to use a pre- PCB that used the same components with some changes because it was dealing with 25 Amp. output current.
The question is :
* could you give me the main components I have to change in order to make a suitable design without any problem in testing it?
* could you tell me which parameters I have to test in order to say that my design is working good?
Thanks in advance.
greetings,
Mido

PWM switched Inverter

calculate and check out IGBT losses both their switching and conduction losses,

analyze the performance if it gives efficiency above 90% then it is good enough.
