Hello MATLAB Power electronics experts,
I am designing MATLAB modeling of Bridgeless Boost PFC converter.
I have some questions about how to control gate signals for both MOSFETs in Bridgeless Boost PFC conveter as the below picture.

When I applied fixed duty cycle as 48% at switching frequency 20kHz
The shape of Vout is kinds of positive half cycle of AC input voltage as you can see the below waveform.

My purpose is to make DC output voltage around 400V when input voltage is 220V, 60Hz.
However, I don't know how to make DC output voltage from current my modeling.
Could you please check my simulink data and give me feedback and solution?
I attached my simulink data with MATAL2020b, 2019b, 2018b.
Please check my data.
I would really appreciate your support if you could find a solution.
Thanks
Best regards
