Other Parts Discussed in Thread: UCC28220

Hi Dragan / all,PV input range : 25V to 55VDC

i want to boost it to 380V / 400VDC. Can i go with interleaved flyback or interleaved boost controller ic for dc to dc conversion.

Can i use UCC28220 interleaved flyback IC. anyone suggest me hw much the transformer ratio will be suitable for this.

Hi Suresh,

Flyback transformer ratio for D=0.66 max @ 25v is 1 : 5.3

Hi Dragan,

Can you suggest me, what should be the DC bus / DC-link voltage for Micro Inverter. i.e., after DC-DC conversion. (either 220VDC / 400VDC).

Hi Dragan,

Can you suggest me the duty cycle & flyback transformer turns ratio for 400VDC (dc-link voltage) with 100VAC and 220VAC.
