OFF-LINE POWER SYSTEM Russian patent published in 2003 - IPC

FIELD: off-line power systems for space vehicles. SUBSTANCE: system has n power supplies connected through respective regulator to output leads. Each regulator has control unit whose output is connected to control input of regulating element of respective regulator and input, to n inputs of current sensor of this regulator and to regulator output voltage sensor through respective adding unit. Each input of adding unit is connected to output of one of output voltage sensors; each regulator is provided with two n- contact plug connectors. Each of n inputs of adding unit is coupled with like polarity contacts of both plug connectors; output-voltage sensor output is coupled in each regulator with input common for all adding units. Mating part of first connector of regulator is connected via n-circuit cable to mating part of preceding-regulator second connector and mating part of second connector is coupled via n-circuit cable to mating part of next-regulator first connector; all n cables have their contacts interconnected so that they are offset by one contract, and all n cables are identical. Off-line power system enables replacement of failed regulators in the course of system operation, variation of its installed capacity by disconnecting or connecting part of regulators, and parallel operation of regulators with input of any adding unit in case of open circuit in one of outputs of output voltage sensor. EFFECT: enhanced reliability; enlarged functional capabilities. 1 cl, 1 dwg
