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 (Figure 3) control scheme. The output voltage of the HAM is a function of incoming AC line voltage (Figure 3). On a nominal 115 Vac line, the output voltage of the HAM is 280 Vdc — well within the input operating voltage range of Vicor V375 DC-DC converters. Above 180 Vac input, the output voltage linearly increases with input voltage. At 230 Vac the delivered voltage will be approximately 365 Vdc. 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 sacrificing operating efficiency.
