The invention discloses a manufacturing method of a three-level energy storage converter based on A-NPC topology, belonging to the technical field of new energy sources and energy storage. The methodof the invention specifically comprises the following steps: determining the circuit structure of the main circuit, determining the hardware structure of the control system and determining the software strategy of the control system. An energy storage converter system is built based on a neutral point clamping three-level topology of an inverse resistance type IGBT, can realize smooth voltage andcurrent output under grid-connected operation condition, and has that characteristics of high conversion efficiency, high power factor, small current harmonics and the like. For distributed energy storage system and centralized energy storage system, the design value of inductance of a filter circuit can be reduced, so that the overall size of the system can be reduced to increase the power density, and the miniaturization and modularization of the energy storage system can be facilitated. In addition, the increase of converter system power can increase the energy utilization rate of the energy storage system, thereby reducing the input cost of energy storage carrier, which has social and economic benefits of energy conservation and emission reduction.
