The HAM Figure 1, consists of a full-wave rectifier, a
high-frequency zero-current switching (ZCS) boost converter,
active inrush current limiting, short-circuit protection, control
and housekeeping circuitry. The incoming AC line is rectified
and fed to the boost converter. The control circuitry varies the
operating frequency of the boost converter to maintain the
output voltage of the HAM above the peak of the incoming
line, while forcing the input current to follow the waveshape
and phase of the line voltage. The AC input current follows the
voltage waveform and a power factor better than 0.99 is
achieved. Operating efficiency of the boost converter is
optimized at any incoming line voltage by an adaptive output
voltage control scheme.
The output voltage of the HAM varies as a function of
incoming AC line voltage, Figure 3. On a nominal 120 Vac line
the output voltage of the HAM is 260 Vdc — well within the
input operating voltage range of Vicor VI-26x and VI-J6x
converters. As input line increases, so does the HAM output
voltage; at 220 Vac the delivered voltage will be about 350 V.
For any given input line voltage, the HAM maintains enough
headroom between the output voltage and peak input voltage to
ensure high quality active power factor correction without
unnecessarily sacrificing operating efficiency.
