hello everyone,
i need help to calculate the inductor and capacitor value in z source inverter please
thanks in advance
 

Z Source Inverter.jpg
Input voltage: Vin
Output voltage: Vout
Time period of PWM: Tpwm
Time period of carrier wave: T
Inductor peak to peak current: Lir (50-60%)
Capacitor voltage ripple: Cvr (20-30%)
Inductor current: IL(Pout/Vin)
Maximum current: Imax (IL + IL*Cvr)
Minimum current: Imin (IL - IL*Cvr)

Voltage ratio: VR =Vout/Vin

Shoot through duty cycle: Ds =VR-1/2VR

Time period of shoot through duty cycle: Ts = Ds x T

Capacitor voltage : Vc = Vin + Vout/2

Average inductor current: DIL = Imax – Imin

Required Inductance L = Ts x Vc/DIL

Required capacitance C = IL x Ts/Vc x Cvr
