Key Terms

power factor correction technical

Power factor correction is the practice of improving how efficiently an electrical system uses delivered electricity by reducing the gap between the voltage supplied and the current drawn. Like tightening the fit between a key and a lock so less effort is wasted, correcting power factor lowers wasted energy, can reduce utility charges and equipment strain, and may affect a business’s operating costs and capital needs.

pmbus technical

PMBus (Power Management Bus) is an open digital communication protocol used to monitor and control power supplies and power-management chips inside electronic systems. It matters to investors because PMBus-enabled products let manufacturers remotely read voltage, current and temperature and adjust power settings, improving reliability, shortening development time and enabling smarter features—like a dashboard and remote controls for a device’s power system— which can influence product competitiveness and sales.

inrush limiting technical

Inrush limiting is a set of techniques and devices that reduce the brief surge of electrical current drawn when equipment or motors start, using components like resistors, thermistors, soft starters, or current-limiting transformers. It matters to investors because controlling that startup spike protects electrical systems, reduces the need for oversized infrastructure, lowers maintenance and downtime risk, and helps meet grid or safety rules—like preventing a traffic jam at rush hour so the system doesn’t overload.

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

DENVER--(BUSINESS WIRE)-- Advanced Energy Industries, Inc. (Nasdaq: AEIS), a global leader in highly engineered, precision power conversion, measurement and control solutions, today 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.

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

Advanced Energy’s AIH03ZPFC is designed for applications in industrial, medical, defense and telecommunications systems where size, thermal performance and efficiency are critical. Featuring a regulated, non-isolated 390 V_DC 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.

"This represents a significant advancement in power design, enabled by proprietary AE technology,” said David Richmond, Advanced Energy’s senior vice president, High Volume Products. “By combining 1100 W of power with extensive integrated functionality, Advanced Energy's AIH03ZPFC reduces losses by 46% compared to prior designs and sets new standards for power delivery, peak efficiency and capability in a half-brick PFC module."

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.
