摘要

These serially connected converters have multiple regulation modes including a new normal mode in which the current-versus-voltage characteristic has a substantial negative slope. This mode produces better load sharing among the serially connected converters than would a constant-current mode of operation and provides more stable operation of the remote repeaters serially supplied along a communication line by the converters than would a constant-voltage mode of regulation of the converters, especially in the presence of disturbances on the line. In the event that a converter is turned on into a line presenting an abnormally high load impedance, the converters are shut down. In the dual-line communication link, the neutral point at the floating end is grounded in the presence of sufficient voltage inbalance and then is ungrounded when the line currents are near balance.
