Variable swithing frequency for Bridgeless boost converter

1 次查看(过去 30 天)
Hi every one! I have a question about variable switching frequency for bridgeless boost converter to control the output voltage. would you please guide me on how generate variable pulse by using the error signal of measured output voltage and reference output voltage? I know that the frequency of this system should be maximum when input voltage cross zero and minimum when input voltage is maximum.

Hi,
I understand that you want to know how to generate variable pulse using error signal.
You can use “variable pulse generator” block or “PWM” block in Simulink.
The input to the block can be the error signal with appropriate signal processing or control logic and the output will be pulse with variable switching frequency.
Please refer to the documentation attached below to get more information on the two blocks.
Also, refer to the example model of boost converter implementing variable pulse generation logic.
