configuration triples the output voltage and doubles the output current. If a series/parallel config-
uration is enabled, communication between the master BOP and those configured as slave
units occurs via the BITBUS. Refer to PAR. 2.8 for further details.

ENERGY RECUPERATION
The BOP is a four-quadrant device as shown in Figure 1-3. Operating as a source, it delivers
energy into a passive load, and as a sink it operates as an electronic load, absorbing and dissi-
pating energy from an active load. To minimize energy dissipation, the BOP employs energy
recuperation, where energy sinked from an active load is passed backwards through the output
circuit and the bidirectional input power factor correcting circuit to the a-c power lines, where it
becomes available for reuse. This technology allows high power levels using switch-mode tech-
nology while maintaining high efficiency and reduced size and weight.
