The key to this Conventional d-c power supplies operate in is a bi-directional a-c input power factor correcting (PFC) circuit, which allows a single quadrant of the voltage-current transparent energy interchange without dissipative internal sinking. axis, delivering stabilized and adjustable d-c voltage or current to a load. They may be voltage stabilized, meaning that the current varies with the load, or they may be current stabilized, meaning that the voltage varies with the load. Kepco's BOP operate in all four quadrants of the voltage-current axis, therefore their output may swing seamlessly from negative to positive voltage and the output current may also swing from positive to negative The BOP 1KW has two primary control channels: voltage or current. Either of these may values. The result of this is that BOP will be controlled from full plus setting to full minus setting. To assure that they will intersect in one of the two source quadrants to form a closed boundary as do function as a source or a sink, meaning it conventional unipolar power supplies, four auxiliary limit channels are provided: will either deliver power to a load or absorb plus voltage, minus voltage, plus current and minus current. These four are controllable power from a load. In order to do that, the from a very small value to the nominal values. Their control does not pass through BOP is built as a power amplifier with a zero as do the primary voltage and current channels. The intersection of whichever bipolar output, having a frequency band- primary control channel is engaged by the load and the respective limit channel does width much larger than a regular power form a closed boundary, and a variable load automatically crosses supply. The frequency bandwidth is model over from the primary channel to the limit channel. and option dependent. 2 1 BOP 1KW MODEL TABLE + CURRENT LIMIT d-c OUTPUT RANGE CLOSED LOOP GAIN OUTPUT IMPEDANCE MODEL VOLTAGE CURRENT VOLTAGE CURRENT VOLTAGE MODE CURRENT MODE V d-c A d-c CHANNEL CHANNEL SERIES R SERIES L SHUNT R SHUNT C G (V/V) G (A/V) V I mΩ µH Ω µF 1000 WATT BOP 6-125MG 0 to ±6 0 to ±125 0.6 12.5 0.05 1.5 24 1150 – CURRENT LIMIT BOP 10-75MG 0 to ±10 0 to ±75 1.0 7.5 0.13 2.0 67 976 BOP 20-50MG 0 to ±20 0 to ±50 2.0 5.0 0.40 8.3 200 371 BOP 25-40MG 0 to ±25 0 to ±40 2.5 4.0 0.63 15.8 313 165 3 4 BOP 36-28MG 0 to ±36 0 to ±28 3.6 2.8 1.30 25 640 103 FOUR-QUADRANT OPERATION BOP 50-20MG 0 to ±50 0 to ±20 5.0 2.0 2.50 50 1250 55 FROM A KEPCO BOP POWER SUPPLY BOP 72-14MG 0 to ±72 0 to ±14 7.2 1.4 5.14 104 2570 33 BOP 100-10MG 0 to ±100 0 to ±10 10.0 1.0 10.0 163 5000 16 In quadrant 1 of the volt-ampere axis, both voltage and current are positive so the BOP power supply NOTE: When connecting active loads, the steady-state voltage of the active load must not exceed the maximum voltage rating of the BOP.
