Can a half-brick power module deliver more without increasing footprint? A compact design is pushing density and efficiency further.
Advanced Energy Industries has introduced an 1100 W board-mounted power factor correction (PFC) module in a half-brick form factor, targeting applications where power density, thermal performance and system size are critical. Designed for industrial, medical, defence and telecommunications equipment, the module integrates functions typically implemented as separate components, helping simplify power system design.
The design aims to reduce both board space and overall system complexity by combining inrush current limiting and digital management within a single package. Integrating these capabilities eliminates the need for additional external circuitry, allowing engineers to build more compact power architectures while reducing design overhead. The module also provides auxiliary power support for housekeeping functions, further contributing to smaller power supply implementations.
The PFC module delivers a regulated, non-isolated 390 VDC output with a peak efficiency of 97.3%, representing a 2.3% improvement over the company’s previous generation. It increases power density to 380 W/in³, a 44% improvement, while reducing power losses by 46% compared to earlier designs. Digital PMBus control and monitoring provide visibility into operating conditions, while a unity power factor across an 85 VAC to 264 VAC input range simplifies compliance. The design also maintains full output without derating at low input voltages and can operate either as a standalone PFC stage or alongside downstream DC-DC converters.
The module uses baseplate contact cooling to support operation from -20°C to +100°C, with startup capability down to -40°C. Packaged in a standard 61 × 58.4 mm half-brick footprint with a height of 13.3 mm, it is compatible with standard heatsinks and thermal solutions.
“This represents a significant advancement in power design, enabled by proprietary AE technology,” says David Richmond, Senior Vice President, High Volume Products at Advanced Energy Industries. “By combining 1100 W of power with extensive integrated functionality, the design reduces losses by 46% compared to prior designs while improving efficiency, capability and power delivery in a half-brick PFC module.”
