Unity Power Factor

VI-HAM

Conventional capacitive-input front ends draw

energy from the AC line in short bursts of current

at the peaks of the line voltage waveform. These

current bursts are characterized by high peak

currents and high harmonic content. The effect of

the distorted line current can be appreciated by

measuring the rms line current drawn by a

conventional front end: the product of the

measured rms current and the rms line voltage —

the "apparent power" being delivered by the line

— will be significantly greater (typically 1.6X)

than the DC power delivered by the front end.

The "extra" rms current at the input is circulating

harmonic currents which deliver no power to the

load but which flow in the delivery system and

contribute to losses. Only the fundamental

The VI-HAM also includes active circuitry which

controls inrush currents when power is applied

and active short circuit protection circuitry —

features not normally found in conventional power

factor correctors.

Features

Housekeeping circuitry provides two signals of

use to the system designer (see Fig. 2): Module

Enable and Power OK. Referencing the timing

diagram (see Fig. 3), the Module Enable signal,

which is connected to the Gate In inputs of the

Vicor DC-DC converters powered by the

VI-HAM, will come high and enable the DC-DC

converters when the VI-HAM output voltage

exceeds 240Vdc. The DC-DC converter voltage

outputs will be up approximately 10 ms after

Module Enable goes high. Typically, 20 ms after

Module Enable goes high the VI-HAM Power OK

signal, which can be used by the system designer

to enable circuitry powered by the DC-DC

converter modules, goes low. On loss of power or

brownout, the Power OK signal will go high when

the VI-HAM DC output voltage drops below

230V, signaling an impending loss of input power

to the converter modules. When the DC output

dips below 195V, the Module Enable signal will

toggle low, disabling the converter modules and

unloading the VI-HAM. The VI-HAM will

provide at least 16 ms of ride-through or holdup

time, and at least 5 ms of AC fail warning time

with a 1000 µF output capacitor.

component of the line current contributes to "real"

power flow. Power factor — the ratio of "real" to

"apparent" power — is a measure of the

effectiveness with which an AC load can extract

usable power from an AC source.

The VI-HAM (see Fig. 2) consists of a

full-wave rectifier, a proprietary high-frequency zero-

current switching (ZCS) boost regulator (patents

applied for), active inrush, short-circuit protection,

control and housekeeping circuitry. The incoming

AC line is rectified and fed to the ZCS boost

converter. The 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 AC input

current follows the AC voltage waveform and a

power factor better than 0.99 is achieved.

Operating efficiency of the ZCS boost converter is

optimized at any incoming line voltage by a

patented adaptive output voltage control scheme.
