Zusammenfassung:The invention provides a double-bus solar cell array power redundancy expansion device. Comprising a solar cell sub-array SAS1, a solar cell sub-array SAS2, a first shunt module, a first push-pull circuit, a redundancy expansion control system, a first voltage division circuit, a second shunt module, a second push-pull circuit, a second voltage division circuit, a hysteresis comparator, a fourth triode, a first operational amplifier and a second operational amplifier, the other end of the solar cell sub-array SAS1 is respectively connected with the first shunt module, the redundancy expansion control system, the first voltage division circuit and the + 42V power supply bus; and one end of the solar cell sub-array SAS2 is grounded, and the other end of the solar cell sub-array SAS2 is connected with the second shunt module, the redundancy expansion control system, the second voltage division circuit and the + 28V power supply bus. The method has the beneficial effects that a power interconnection path is estab
