dc bus

Hello all, How do they calculate the split DC-link capacitors and the balancing resistors in the below image? The circuit is a 10-kW, Bidirectional Three-Phase Three-Level (T-type) Inverter by TI. Thank you,

Hi! I would need some clarification with a BLDC DC bus current.(Marked With IL on the picture) The motor is a BLDC with trapezoidal commutation and 20kHz PWM. I beleive that current is the 20 kHz PWM with an amplitude of the maximum current of the motor. Is it right or I misunderstood...
