OZip-AFE provides a complete Active Front End (AFE) solution for OEMs. Built upon Oztek’s OZip-R1230H Intelligent Power Module, the compact, open frame system includes power circuitry, controls, grid interface filter, switchgear, cooling fans, bias supply, and control software, ready for integration into your electrical enclosure. OZip-AFE gets you to market quickly, minimizing development cost and risk, while also being more cost-effective in production volumes.
OZip-AFE provides bidirectional power transfer between an AC power input and an intermediate DC link, while maintaining low distortion, sinusoidal AC line currents. It operates as a rectifier when transferring power from the AC line to the DC link, and as an inverter in the opposite direction.
OZip-AFE provides numerous application advantages. The ability to absorb as well as deliver power eliminates the need for large braking resistor banks in regenerative systems, saving size and cost, reducing waste heat, and improving efficiency. The inherently low current harmonic distortion meets IEEE 519 specifications. Power factor defaults to unity, but reactive current levels can also be programmed to offset non-unity power factor from other loads. The DC link voltage is boosted and regulated, greatly reducing end-equipment sensitivity to line voltage variations.
