摘要（英）：

The invention belongs to the technical field of power system control, and particularly relates to a resonant filter-based full-bridge MMC DC deicing device and a design method thereof. The device comprises a circuit breaker, an isolating switch, a connection reactor, a resonant filter-based full-bridge MMC, four deicing disconnectors and a to-be-deiced AC line which are sequentially connected. The method comprises the steps of: determining a coverage line range of the DC deicing device; calculating deicing current of each guide wire within the coverage line range; calculating DC voltage and DC power according to the deicing current and a deicing connection mode; calculating the number of sub-modules of the full-bridge MMC DC deicing device; calculating capacitance values of sub-module capacitors of the full-bridge MMC DC deicing device; calculating a reactance value of a bridge arm reactor of the full-bridge MMC DC deicing device; and calculating parameters of a resonant filter.
