Hi Team,
Good day, we received inquiry from customer and want to design a 15kW interleaved two-phase boost converter with an output of 550V and an input varying from 180V to 320V using UCC28220. The voltages V1 - V4 are received by stepping the high input down with a resistor divider connected to a voltage buffer.
In his design, he wants to have the following voltages V1 =3,89V; V2= 5V; V3 = 9,17V; V4=10V . However, using the equation 6-9 the value of R1-R4 ( R1=1,22 / R2=0,031 / R3=0,019 and R4=1,22) are too small. The customer want to know if it is possible to have higher resistor value using this voltage parameters to build 15kW interleaved two-phase boost converter.
Thank you and looking forward for your kind response.
Regards,
Maynard
