Zusammenfassung:	The invention provides a voltage conversion circuit. The circuit comprises a first digital-to-analog converter, a second digital-to-analog converter and an operation conversion module. The input end of the first digital-to-analog converter receives a polarity instruction output by a first configuration device according to a test requirement, and the output end outputs a first voltage or a second voltage. The input end of the second digital-to-analog converter receives a gray-scale information instruction output by a second configuration device according to the test requirement, and the outputend outputs a gray-scale alternating current voltage. The first input end of the operation conversion module is connected to the output end of the first digital-to-analog converter, and the second input end of the operation conversion module is connected to the output end of the second digital-to-analog converter. According to the first voltage and the second voltage, the output end of the operation conversion module outp
