Designed for use as an AC front-end, the AIH03ZPFC half-brick PFC converter provides a high-power power factor correction solution for systems that require a regulated high-voltage DC bus. It accepts standard worldwide 90–264 VAC mains input or 127–373 VDC input and delivers a nominal 390 VDC output for one or more downstream DC-DC converters. With peak efficiency up to 97.3%, it helps reduce conversion losses and thermal burden in dense power architectures. The module integrates active inrush current limiting to simplify startup design and reduce external component count. A PMBus digital interface enables system-level monitoring and control of key operating parameters. An auxiliary bias output is also included to support control electronics or cooling fans. Its industry-standard half-brick footprint supports compact, high-density designs. The fully encapsulated construction and wide baseplate operating range from -40°C to +100°C make it suitable for harsh industrial, aerospace, defence, and telecommunications environments.
The AIH03ZPFC is a non-isolated half-brick PFC front-end module designed to generate a regulated high-voltage DC bus from global AC mains input. It is well suited for distributed power systems where a compact, efficient AC-DC front end must feed isolated downstream DC-DC converters.
Key integration advantages include digital PMBus monitoring, internal inrush limiting, auxiliary bias output support, and a compact package that enables high power density in space-constrained equipment.

FAQs
for AIH03ZPFC Series – Active 1100 W 1/2 Brick PFC DC/DC Converter
The AIH03ZPFC accepts 90 to 264 VAC or 127 to 373 VDC input and provides a regulated high-voltage DC output of about 390 VDC. It is intended to feed downstream DC-DC converter stages that generate the final application voltages.
No. The module uses a non-isolated boost topology, so the output is not isolated from the input source. It is designed as a front-end PFC stage and should be paired with isolated downstream converters where safety isolation is required.
The converter reaches up to 97.3% efficiency under specified conditions. This high efficiency helps reduce heat generation and supports compact, high-density power system designs.
The AIH03ZPFC integrates an inrush current limiter, a PMBus digital monitoring and control interface, and an auxiliary bias output. These features help reduce external circuitry, improve system visibility, and simplify overall front-end design.
The module includes a PMBus-compatible interface over I2C for digital control and telemetry. This allows monitoring of parameters such as voltage, current, and temperature, while also supporting supervisory control from a system controller.
The AIH03ZPFC is intended for conduction cooling through its baseplate and supports an operational baseplate temperature range of -40°C to +100°C. Proper heatsinking or cold-plate attachment is required to maintain rated performance.
This module is well suited for industrial, telecommunications, aerospace, defence, and other high-reliability systems that need a compact, efficient AC front-end stage with a regulated high-voltage DC bus.
