The full bridge modular multilevel converter（MMC） DC deicing technology

as a kind of novel technology

is more complicated over that of thyristor.Its related testing technology is still under initial stage;therefore comprehensive test is needed to assure the manufacturing reliability of the device.In view of above reason

in this paper

the testing technology of type MMC DC deicing device is analyzed and studied in detail

and a complete set of testing technology for this kind of deicing and STATCOM device.The basic operating principle based on the deicing technology is introduced firstly

then

the testing method for the de-icing device is designed.Finally

the simulation is performed in PSCAD and the correctness of the testing technology is verified with the first set of mobile full bridge MMC DC deicing technology and STATCOM device as example.
