1,100-W PFC Module Touts Highest Power Density in a Half-Brick Form Factor
With 1,100 W in a half-brick form factor, Advanced Energy Industries’ AIH03ZPFC power-factor-correction (PFC) module is said to be the industry’s first device of its kind. Featuring a regulated, non-isolated 390-V DC output, the module delivers up to 97.3% efficiency, which represents a 2.3% improvement over the company’s previous generation of PFC modules. As a result, these new DC-DC converters increase power density by 44% to 380 W/in3.
The AIH03ZPFC module is designed for applications in industrial, medical, defense, and telecommunications systems where size, thermal performance, and efficiency are critical.
It includes internal inrush limiting as well as digital PMBus control and monitoring, both features not typically associated with half-brick designs. Auxiliary power support enables external housekeeping functions while maintaining a compact footprint, allowing for further miniaturization of end users’ power systems.
A unity power factor across a wide input range of 85- to 264-V AC 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- × 2.3-in. (61 × 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 opens the door to high-density system designs while enhancing performance visibility and control.
