Boost Converter in Simulink

I am designing a boost converter on simulink which works with IGBT. The input of my IGBT is a PWM generator with duty cycle constant fed. However, my Vout = Vin when my duty cycle is at 0.5. It should be Vin = 2Vout when duty cycle is 0.5.

The components parameter is as such. Capacitor1: 50E-6F, Capacitor2: 10E-6F, Inductor: 2.6E-3H, Frequency: 40kHz, Resistance: 1664 ohms, Vin: 100V.

My simulink model can be found in this link. http://workupload.com/file/ToTip5Ys

Appreciate to those who can indicate whats wrong with this boost converter! Thanks in advance!
