Document Type and Number:
WIPO Patent Application WO/2024/031223
Kind Code:
A1
Abstract:
Disclosed in the present invention is an energy-saving and parallel superposition wiring method for a three-phase CSR rectification circuit. The method comprises: outputting two windings at a low-voltage side of a power distribution transformer for power supply, wherein the two windings respectively supply power to two CSR half-bridge rectification circuits, the voltages of the two windings are equal, and corresponding phases are the same. Each of the windings is connected to a CSR non-full-bridge loop, two CSR non-full-bridge loops operate at respective operation times, the operation times correspond to an angle interval of 60°, and an alternate operation mode is formed and the times are complementary, such that a full-bridge CSR high-frequency rectification function is completed. By means of the energy-saving and parallel superposition wiring method for a three-phase CSR rectification circuit provided in the present invention, the number of switch tubes decreases, the power consumption is reduced, a withstand voltage is high, a power factor is large, a harmonic wave is small, and the power increases.
