The controller comprises a lower computer module used for communication, analog quantity acquisition, instruction control, DA setting and software MPPT algorithm implementation, a filtering module used for placing a bus filtering capacitor, reducing bus output impedance and improving dynamic response, a signal module used for obtaining +/-12V power supply required by the power supply controller from a 400V bus and obtaining a bus voltage signal VMEA, and a power module which is used for power conversion, adjusting bus voltage under the condition that the power of a solar cell array is sufficient, and realizing the maximum power tracking of the solar cell array under the condition that the power of the solar cell array is insufficient. According to the four types of modules, connection between control signals and power signals among the modules is realized through a backboard. With the high-voltage bus power supply controller applied to space adopted, the efficiency can be improved, the weight can be reduced, the high voltage step-up ratio from the solar cell panel to a high-voltage bus is achieved, and meanwhile maximum power tracking of the solar cell panel is achieved.
