S-ⅣB 级电气系统为飞行任务提供和分配全部交流和直流电源。它包括两个主要的分系统:一个是电源分系统,它由级的所有电源组成,如一次电源(电池)和二次电源(预冷变换器、推进剂利用静态变流器和各种激励组件)。一次电源有四组电池,这四组电池分别能提供28伏和56伏直流电。两组电池安装在前裙段,两组电池安装在后裙段;另一个是电气控 The S-IVB electrical system supplies and distributes all AC and DC power for missions. It consists of two main subsystems: one is the power subsystem, which is made up of all the stages of the power supply, such as primary (battery) and secondary (pre-cooling converters, propellants utilizing static converters and various stimuli Component). A power supply has four batteries, the four batteries were able to provide 28-volt and 56-volt DC. Two sets of batteries installed in the front skirt section, two sets of batteries installed in the skirt section; the other is electrically controlled
