The invention provides a control recorder based on voltage crossing test. The output of an adjustable transformer is controlled, and voltage and current values of the adjustable transformer and a transformer load are acquired in real time. The control recorder comprises a central controller which is connected with the adjustable transformer and the load, controls the output voltage magnitude and the maintenance time of the adjustable transformer, and assesses the voltage crossing ability of an inverter, a signal acquisition and processing module, a waveform analysis module, a graph display module and a compression storage module. The input end of the signal acquisition and processing module is connected with the central controller and the adjustable transformer. The input end of the waveform analysis module is connected with the central controller and the signal acquisition and processing module. The input end of the graph display module is connected with the central controller and the signal acquisition and waveform analysis modules. The input end of the compression storage module is connected with the central controller and the signal acquisition and processing module. The control recorder provided by the invention has the advantages of automated test and labor cost saving.
