230V, 3.5kW PFC reference design with greater than 98% efficiency, BOM and size optimization

TIDA-00779

Overview

TIDA-00779 is a 3.5kw affordable power factor regulator converter designed for room air conditioners and other large appliances. This reference design is a continuous conduction mode (CCM) boost converter and is implemented using the TI UCC28180 PFC controller and all the necessary built-in protection mechanisms that come with it. The hardware design has been tested and passed IEC61000 surge and EFT test requirements for household appliances.

characteristic

● Achieve high efficiency greater than 98% over the entire operating voltage range, thus reducing the size of the heat sink
● Wide full-load operating input voltage range: 190 VAC to 270 VAC
● High power factor greater than 0.99 and THD less than 5% from medium load to full load (50-100%)
● High power output up to 3.5kw, covering most single-phase input PFC applications
● 8-pin PFC solution (no AC line sensing required) makes design easy
● Reduced current sensing threshold minimizes power dissipation
● High power density helps reduce size
