suggest boost converter pwm controller with PFC

hi,

I m going to design a front end single phase boost converter with power factor controlled.the specifications are given below.

Input voltage : 160-300Vac

Boost output voltage : 400 Vdc

Current : 20A

Power : 8kW

I request you to suggest a suitable PWM controller IC with power factor correction for boost converter.

  • 2x UCC28070 connected. You can even connect 4x UC28070 in parallel (see datasheet). You need external clock.

  • Manikandan,

    With a 300 Vac input you will have to increase your output voltage beyond 400 volts. The peak of a 300 volts AC  is over 420 volts. You will want at least a 450 volt output.  

    Regards,
