BOP 1 KILOWATT MODEL TABLE

The BOP 1 Kilowatt has two primarycontrol channels: voltage and current.Either of these may be controlled fromfull plus setting to full minus setting. Toassure that they will intersect in one ofthe two source quadrants to form a closedboundary, as do conventional unipolarpower supplies, four auxiliary limit channels are provided: plus voltage,minus voltage, plus current and minuscurrent. These four are controllable fromzero to the nominal values. Their controldoes not pass through zero as do the primary voltage and current channels.The intersection of whichever primarycontrol channel is engaged by the loadand the respective limit channel doesform a closed boundary, and a variableload automatically crosses over from theprimary to the limit.

Conventional d-c power supplies operate in a single quadrant of thevoltage-current axis, delivering stabilized and adjustable d-c voltage orcurrent to a load. They may be voltage stabilized, meaning that thecurrent varies with the load…or they may be current stabilized, meaningthat the voltage varies with the load. Typically, a large output capacitoris used to filter out ripple and noise and to provide dynamic stabilityat the expense of voltage change speed.

Kepco's BOP operate in all four quadrants of the voltage-current axis,therefore their output may swing seamlessly from negative to positivevoltage and the output current may also swing from positive to negativevalues. The consequence of this is that BOP will function as both asource and a sink, meaning it will either deliver power to a load orabsorb power from a load.

The output of Kepco’s BOP 100-400 Watt models feature capacitorlessfiltering and the BOP 1 Kilowatt models feature low capacitance filtering, using the high gain of the feedback amplifiers to suppress ripple and noise. Freed of the constraints of a large shunt capacitor, BOPhave relatively wide bandwidth making them capable of following a rapidly changing load in current stabilizing mode, or able to reproducehigh frequency programmed voltage changes from either an analogsource or a digital bus.

BOP range from 100-400 Watt models employing linear topologyto 1000 Watt models employing switch mode topology with energyrecuperation and power factor correction. There are high voltagemodels, too.

APPLICATIONS FOR KEPCO’S BOPAutomotive (Battery and Motor Simulation and Testing),

Wafer Deposition and Electroplating,

Magnet Applications (Beam Steering, Medical Imaging, etc.),

and Solar Panel Research and Testing

In quadrant 1 of the volt-ampere axis, both voltage and current are positive so the BOP power supply is able to deliver power to a load. In quadrant 3 both are negative and the BOP is also asource. In quadrants 2 and 4, however, the voltage and current are of opposite polarity. In thesetwo quadrants the BOP will act as a sink, absorbing power. The sinking may be transient in natureas BOP absorbs energy stored in reactive elements or it may be steadystate as BOP controls thedischarge of a battery.

BOP 1 KILOWATT ALLOW FOR AUTOMATIC CREATION AND DISPLAY OF VARIOUSWAVEFORMS AND COMPLEX PATTERNS.

The 1000-watt models have an internalwaveform generator that allows a user tocombine segments of a sinusoidal wave-form, triangular waveform, a ramp, a sawtooth waveform and a square 50% dutycycle pulse, plus d-c to create a variety ofarbitrary waveforms. 3,933 of points perbasic waveform can be programmed witharbitrary phase relationships. The resultingwaveshape can be repeated from 1 to 255times. The waveshape can also be executedindefinitely until a stop command isreceived. The waveshape graphics are displayed on the front panel-mounted LCDdisplay, which also displays both settings andactual d-c output values. The programmedwaveshapes can be used to control eithervoltage or current with both positive andnegative values. It is possible to reproducean a-c sinusoid with differing degrees ofdistortion or dropouts for test purposes.Alternatively, varying amounts of “noise”can be added to a d-c output to gauge theeffect on a test subject.

SUPER FAST, DYNAMICALLY RESPONSIVE BIPOLAR POWERLINEAR BOP

The Kepco Model BOP500M and BOP 1000Mare high voltage powersources, up to ±500V or±1000V, respectively. Thesecombine the capabilitiesof fast programmablepower supplies with aClass A output stage, which can respond bi-directionally fromzero. They can be operated in either a “voltage stabilizing” or“current stabilizing” mode. For full specs, visit our Web site atwww.kepcopower.com/bophv.htm.

BOP, while fully rated power supplies, are alsohigh-powered operational amplifiers with full4-quadrant, bipolar operation. Their output iscapable of both sustained d-c and the replicationof arbitrary a-c waveforms. Voltage and currentoutputs can be controlled smoothly and linearlythrough the entire rated plus and minus ranges,passing smoothly through zero with no polarityswitching.
