Part Number: TIDA-00364
Hi,
This is Kalyanraj, currently working on the 5kW PMSM drive system.
spec:
input voltage: 36-60V (battery)
Fsw: ~20kHz
output current max: 136A
Due to size constraints, we are facing some issues with DC link capacitor and inrush current protection implementation. I request you to clarify on the below points,
1. For the given spec, calculated ripple current value is ~ 70A. For this much high current, number of capacitor need to be used is more (say 20).
Is it recommended to operate the system without these capacitors? (Battery may supply the ripple current to inverter)
2. If DC link capacitor is mandatory, for this voltage range (60V max) inrush current protection is needed or not?
Regards,
Kalyanraj D
