AIH03ZPFC Series 1100 W 1/2 Brick PFC Converter

Advanced Energy Develops 1100 W PFC Module with the Industry’s Highest Power Density in a Half-Brick Form Factor

The AIH03ZPFC integrates inrush control and digital management to reduce system size and complexity.

Advanced Energy Industries, Inc. (Nasdaq: AEIS) has announced a new 1100 W board-mounted power factor correction (PFC) module — the industry’s first solution of its kind in a half-brick form factor.

Advanced Energy’s AIH03ZPFC is designed for applications where size, thermal performance and efficiency are critical. Featuring a regulated, non-isolated 390 VDC output, the module delivers up to 97.3% peak efficiency — a 2.3% improvement over the company’s previous-generation PFCs — and increases power density by 44% to 380 W/in³.

The module includes features not typically associated with half-brick designs, such as internal inrush limiting and digital PMBus® control and monitoring. Auxiliary power support enables external housekeeping functions while maintaining a compact footprint, allowing further miniaturization of customer power systems.

A unity power factor across a wide 85 to 264 VAC input range and no power derating under low-input-voltage conditions simplify compliance and maximize usable power. The AIH03ZPFC is compatible with standard heatsinks and thermal solutions and can be deployed as a standalone PFC or paired with downstream DC-DC converters.

Baseplate contact cooling supports -20 to +100°C operation, with startup as low as -40°C. The design features an encapsulated standard 2.4 x 2.3 in (61 x 58.4 mm) half-brick form factor with an installed height of 0.52 in (13.3 mm). Integrating digital control, onboard monitoring, and protection features in a standard half-brick form factor enables high-density system designs while enhancing performance visibility and control.
