1500-W AC switch bridgeless PFC reference design

Description

This reference design is an AC switch bridgeless power factor correction (PFC) that operates with continuous conduction mode (CCM). It takes universal AC-input voltage (90 VAC to 264 VAC): provides 390-V: 1000-W low-line output and 1500-W high-line output. This design uses the UCD3138 digital controller and UCC21220 isolated gate driver. This design achieves 97.1% peak efficiency at 115-VAC input and 98.3% peak efficiency at 230-VAC input. The total harmonic distortion (THD) is less than 1.2% at 115 VAC: 1000 W and less than 2% at 230 VAC: 1500 W. The power factor is greater than 0.997 for both 115 VAC and 230 VAC at full load.
