Product Summary

The VI-HAM-IM is a Harmonic Attenuator Module. It consists of a full-wave rectifier, a proprietary high-frequency zerocurrent switching (ZCS) boost regulator (patents applied for), active inrush, short-circuit protection, control and housekeeping circuitry. The incoming AC line of the VI-HAM-IM is rectified and fed to the ZCS boost converter. The VI-HAM-IM control circuitry varies the operating frequency of the ZCS boost converter so as to simultaneously maintain the output voltage of the VI-HAM at a DC voltage value above the peak of the incoming line, while forcing the input current to the ZCS converter to follow the waveshape of the rectified line. By this means, the VI-HAM-IM AC input current follows the AC voltage waveform and a power factor better than 0.99 is achieved.
