MMC topology 50KW Blocked AC-DC Converter

In July 2020, the 50kW blocked AC-DC converter has been deliverly to State Grid Corporation of China. The internal circuit topology of the power supply is a modular multi-level structure. The sub-module is a full-bridge sub-module that can block DC short-circuit current. The output is 50kW, 5~375V, ±125A, It provides a cost-effective solution for the related tests in the laboratory, which is multi-terminal low-voltage DC distribution network.
