在当今的卫星中,集中式辅助功率调节单元必须提供各种低压,这是有效负载模块所要求的,即使在严重的负载变化下,也要精确且无波动。 因此,功率调节单元非常复杂,必须针对每个有效负载进行定制。复杂的总线系统会将各种电源电压分配给所有有效负载模块。 它们要么直接用于为模块电子设备供电,要么分布式稳压器生成所需的输出电压,该输出电压从中间电压降至<1V。
In todays satellites, a centralized secondary powerconditioning unit must supply a wide variety of lowvoltages, which are required by the payload modules,precisely and without fluctuations even at severe loadvariations. For this reason, the power conditioning unitsare very sophisticated and have to be customized foreach individual payload.A complex bus system distributes each of the varioussupply voltages to all the payload modules. There theyare either used directly to supply the module electronicsor distributed voltage regulators generate the requiredoutput voltages down to <1V from the intermediatevoltage.
