Solar Array Simulator for Small Satellite and method thereof

摘要

A device and a method for simulating output power of a solar cell array for a small satellite are provided to control current-voltage simulation data of the output power satisfactorily and easily at a low manufacturing cost by feeding back load current and voltage. A power supplier(260) supplies power to a system of a small satellite. A storage unit(250) stores simulation condition data for a solar cell array. A power controller(271) generates current-voltage simulation data of the output power by reading the simulation condition data from the storage unit and outputs the control voltage to the power supplied depending on the generated current-voltage simulation data. The power controller calculates a new voltage level and outputs the power corresponding to the new voltage level when a difference between load current/voltage fed back from the power supplier and the current-voltage simulation data of the output power is bigger than a threshold.
