Aircraft static converter detector and detection method

The airplane static converter detector comprises an electric control box and a load box, an adjustable direct-current power supply U is arranged in the electric control box, the electric control box is electrically connected with a static converter to be detected, the static converter outputs alternating current to be connected to the load box, an adjustable resistor is arranged in the load box, and output power supply parameters of the adjustable direct-current power supply U are detected through a direct-current monitoring device. The alternating-current monitoring device detects alternating-current power supply parameters output by the static converter, and the performance of the static converter is judged by adjusting the resistance value of the resistor in the load box to change the value change of the alternating-current monitoring device and the direct-current monitoring device when the power supply load of the static converter is changed. The loading of a fixed load with the precision of 0.1 A can be
