Abstract: With the development of new energy vehicles, problems in the construction of upstream and downstream facilities and supporting infrastructure for electric vehicles have also attracted the attention of researchers. The current electric vehicle charging pile test equipment is expensive and inconvenient to operate. The device designed in this paper using the principle of digital adjustment incremental compensation effectively solves these problems. This paper uses a high-accuracy AD conversion circuit and a digital synchronous tracking amplifier to ensure the accurate and stable output of the power supply. When the maximum increment is ±15%, the actual output power of the switching power amplifier is only 15% of the full-scale power output, and the volume, weight and cost are less than 7% of the original equipment, which meets all current requirements. The test project provides a basis for the large-scale industrialization of related equipment.
