Abstract:
A modular multilevel converter and a power electronic transformer is provided. The modular multilevel converter includes: a low-frequency AC to DC conversion module, comprising three branch circuits connected in parallel between output ends, each branch circuit being formed of multiple IGBT half-bridge circuits connected in series, and an electric coupling point of two adjacent IGBT half-bridge circuits in a middle position of the branch circuit being connected to a voltage input end Vin; a DC to high-frequency AC conversion module, connected between the output ends, the DC to high-frequency AC conversion module being formed of multiple IGBT half-bridge circuits connected in series, the DC to high-frequency AC conversion module having multiple sets of output ends. The MMC and power electronic transformer includes a smaller volume, lower cost and better stability in use.

Claim (Index 10):
