    摘要: A current sharing modular power system including, in each module, an inverter circuit and means to determine the current to a common load from the module. A difference circuit is provided to determine the difference between the module supplied current and the average of the current supplied by the other modules. The difference is then utilized to vary the pulse width of the inverter output so that the pulses are wider if the current from the module is smaller than the current supplied by the other modules and the pulses are thinner if the current from the module is larger than the average current supplied by the other modules. The system also includes a voltage sense circuit to adjust the module operation to maintain a constant voltage output.

    摘要: A fiber optic data link between two points includes a transmitter which serially encodes data and transmits pulses at one rate if DTR is active at the transmitter and at another rate if it is not active. The receiver separates the pulses from the data and tests the pulse rate to decide if DTR at the transmitter is active or not. If no pulses are received, the receiver indicates the data link is not operational.
