Active power factor correction and(PFC Series)

The PF series are Single-Phase, Wide-AC Input Active-Power Factor Correction & Harmonic Attenuation Modules.

This family of front end modules utilize the continuous mode non-isolated boost topology which has the advantage of boosting to a regulated DC output (380Vdc) higher than the peak of the AC input voltage and as a result maintain longer hold up time for the downstream dc-dc converters.

This series of modules can maintain a high power factor close to unity by forcing the input current to follow the shape of the input voltage waveform, and by eliminating any phase difference between both the input current and the input voltage. The PF series of modules reduce the input harmonic distortion level to meet MIL-STD-1399 requirements.

Non sinusoidal waveforms typically contain a fundamental waveform and higher frequency harmonics that contain high percentage of the fundamental. Reducing harmonics distortion is accomplished by forcing the input current waveform to become sinusoidal in shape resulting in a fundamental waveform and low harmonic contents.

These modules operate at a constant frequency of 80kHz to simplify EMI requirements. PFC1000 utilizes a "lossless" passive snubber to reduce voltage stress on components and to minimize noise. Companion filter modules (PFF500 & PFF1000) are available to meet MIL-STD-461 requirements.

PF500 is supplied as a Full Brick product and requires the addition of output storage capacitance. Both PFC500 & PFC1000 are supplied with storage capacitance of 495uF & 1000uF respectively.

All three products contain inrush current limiting.
