The invention relates to the technical field of power electronics, and particularly relates to a cascaded 24-pulse-wave converter topology. The cascaded 24-pulse-wave converter topology comprises a double-Y pulse generator, a phase-shifting transformer set, a four-quadrant 24-pulse-wave converter set and a resistance-inductance load, wherein the double-Y pulse generator is connected to one end ofthe phase-shifting transformer set, the other end of the phase-shifting transformer set is connected with one end of the four-quadrant 24-pulse-wave converter set, and the other end of the four-quadrant 24-pulse-wave converter set is connected with the resistance-inductance load. The device can effectively suppress circulating current, omit an additional circulating current reactor, save the costand reduce the size. In addition, once converter fault circulating current is out of control, only the converter connected with the fault converter in parallel is influenced, and other converters arenot influenced, so that other converters are protected to the maximum extent; four-quadrant operation can be realized; the connection mode of the transformer and the converters enables the network side and the transformer to be balanced in load, the transformer is small in load, and circulating current cannot flow through two secondary sides of the same transformer simultaneously.
