Original Abstract Submitted

an energy-saving and parallel superposition wiring method for a three-phase current-source-rectifier (csr) rectification circuit, includes: providing two windings on a secondary side of a distribution transformer for power supply; supplying power to two sets of csr half-bridge circuits, respectively; and voltages on the two windings are equal, and corresponding phases of the two windings are the same. connecting the two sets of csr half-bridge circuits to the two windings, respectively; the two sets of csr half-bridge circuits operating in respective operation times, and each of the operation times being corresponding to an angle interval of 60�, thereby forming an alternating operation mode and the operation times being complementary, to complete a full-bridge csr high-frequency rectification function. the energy-saving and parallel superposition wiring method is provided that decreases the number of switching transistors, reduces power consumption, improves a withstand voltage and a power factor, reduces harmonics, and increases power.
