The invention relates to a double-bus SAR satellite solar cell circuit, which comprises two sub-arrays: a platform solar array and a load solar array, each sub-array is composed of a plurality of sub-arrays, the same sub-array is composed of a plurality of same solar cell modules connected in parallel, and each solar cell module is composed of solar cells with the same number and same performance connected in series; for each sub-array of the load solar array, solar cells in each solar cell module are distributed in an S shape, and every two adjacent solar cell modules are arranged in an equipotential mode; each sub-array of the platform solar array is arranged on the outer plate, and each sub-array of the load solar array is arranged on the middle plate and the inner plate; the output points of the electric connectors connected between different sub-arrays are mutually isolated, and the positive and negative output points of the same sub-array are mutually isolated, so that the problems of overlarge output point voltage difference caused by working state difference, short circuit of a power supply line caused by redundancy and the like are solved; and the two-wing solar cell circuits are interleaved in parallel to provide power input for the two power supply controllers, so that the reliability of a power supply and distribution link is improved.

    本发明涉及一种双母线SAR卫星太阳电池电路,包括两种分阵:平台太阳阵、载荷太阳阵,每种分阵均由若干个子阵组成,同种子阵由若干条相同的太阳电池组件并联组成,每条太阳电池组件由相同数量、相同性能的太阳电池片串联而成;对于载荷太阳阵各分阵,每条太阳电池组件中的太阳电池成S形布片,相邻两条太阳电池组件采用对等电位排布;平台太阳阵各子阵均布局在外板,载荷太阳阵各子阵布局在中板和内板;不同子阵之间接入的电连接器输出点相互隔离,同一子阵正负输出点之间相互隔离,解决了因工作状态差异造成输出点压差过大、因多余物造成供电线路短路等问题;两翼太阳电池电路交错并联为两台电源控制器提供功率输入,提高了供配电链路的可靠性。
