Conduction Mode

The purpose of this paper is to present an all-SiC switched AC-DC converter using active power factor correction. The typical boost-converter approach is employed using continuous conduction mode. A SiC Schottky barrier diode performs the free-wheeling diode function, and a 600 V, 0.12 % SiC vertical junction field effect transistor performs the switching function under the control of a Fairchild ML4821 integrated circuit. The converter is operable off-line over the full universal voltage range (85-260 VAC), but it was optimized for a 400-600 W application operating at 208 VAC. Results are presented that demonstrate extremely high efficiency at a switching frequency of 500 kHz, the highest operating frequency of the ML4821.
