Quasi-dual-bus satellite power supply controller

Abstract

The invention relates to a quasi-dual-bus satellite power supply controller, and belongs to the technical field of a satellite power supply. The quasi-dual-bus satellite power supply controller comprises a charging regulator (5), a discharging regulator (6), a parallel regulator (7), a filter circuit and a control circuit; the quasi-dual-bus satellite power supply controller is characterized in that the output port of the quasi-dual-bus satellite power supply controller is in parallel connection with a load filter circuit; a platform bus is output by a port I (1) and a port II (2); and a load bus is output by a port III (3) and a port IV (4). The filter circuit is reasonably configured at the output end by the power supply controller provided by the invention, so that the platform bus and the load bus can be isolated to a certain degree; the influence on the platform bus from pulse load generated when the load is in operating is avoided or lowered to the greatest extent; meanwhile, the system configuration can be simplified; and therefore, the quasi-dual-bus satellite power supply controller has the advantages of capabilities of reducing equipment quantity or volume weight, lowering production cost, adapting pulse load special requirements, and the like.

Description

technical field [0001] The invention belongs to the technical field of satellite power supplies, in particular to a quasi-double-bus satellite power supply controller. Background technique [0002] At present, most of the solar-battery power systems of satellites adopt single-bus design. In recent years, due to the requirements of some special loads, the power system is required to have short-term, pulse, and high-power output capabilities; the design of this type of satellite power system adopts a double-bus design, that is, one bus provides power for stable loads, and one Busbars supply pulsed loads. [0003] Single busbar design, that is, all loads share one power supply busbar; the advantage is that the number of equipment in the power supply system is small, the volume and weight are small, and the cost is low; The anti-interference ability and the quality requirements of the power system are relatively high. [0004] Double busbar design, that is, two busbars are de...

Problems solved by technology

[0003] Single busbar design, that is, all loads share one power supply busbar; the advantage is that the number of equipment in the power supply system is small, the volume and weight are small, and the cost is low; The anti-interference ability and the quality requirements of the power system are relatively high

[0004] Double busbar design, that is, two busbars are designed for the power system, one busbar supplies power to stable loads, and the other busbar supplies power to pulsed loads; the advantage is that it can effectively avoid the interference caused by pulsed negatives to stable loads; but there are also many devices in the power supply system , larger weight, higher cost and other disadvantages and problems
