Half-brick converter packs high power density
Advanced Energy’s AIH03ZPFC power factor correction (PFC) converter delivers 1100 W of output power in a half-brick form factor. The board-mount module achieves up to 97.3% peak efficiency and a power density of 380 W/in³. According to the company, this represents a 2.3% improvement in efficiency and a 44% increase in power density over its previous-generation PFC devices.
The AIH03ZPFC integrates features that enhance functionality in a small half-brick design, including internal inrush limiting, digital PMBus control and monitoring, and auxiliary power support for external housekeeping functions. These capabilities make the converter well suited for industrial, medical, defense, and telecommunications systems with demanding size and efficiency requirements.
The AIH03ZPFC provides a 390-VDC output with 1% load regulation, maintains a unity power factor across an 85-VAC to 264-VAC input range, and requires no power derating under low-line conditions.
Baseplate contact cooling supports operation from -20°C to +100°C, with startup at temperatures as low as -40°C. The encapsulated half-brick package measures 2.4 × 2.3 in. (61 × 58.4 mm) and has an installed height of 0.52 in. (13.3 mm).
