I want to ask you is there any chance i can simulate that controller with my power circuit. I dont want to use those BOOT_AVG block. I have not tryied yet , so can you tell if its possible or its gonna be loss of time. The only problem i can see is IRIPA and IRIPB is there a chance to lie somehow the chip.

Hi Ilia,

It is possible to modify the BOOT_AVG block to input your own values for inductance, current sense gain, etc. Is there a specific behavior in your power circuit you are looking to simulate? It is possible to build your own boost power stage into TINA, but it will take some time.

Best Regards,
Ben Lough

Hi

I dont understand how can i simulate my circuit with my own components. The pulses ot PWM outputs are unreal but the system is working
How can i simulate my circuit where i am wrong. I have attached diagram with the signals.

i try to simulate but the frequency on the gates is 50Hz and i can not change that doesn't matter if i use the BOOST AVG blocks or discrete elements
