WIPO Patent Application WO/2022/006691

Kind Code:

Abstract:

Disclosed are a matrix transformer, a power converter, and a method for arranging matrix transformer windings. Magnetic core columns of n sub-transformers of the matrix transformer are each provided with a first winding and a second winding, the first windings are used for forming a high-voltage side winding of the matrix transformer, and the second windings are used for forming a low-voltage side winding of the matrix transformer. The ratio of the designed number of turns of the high-voltage side winding to the number n of the sub-transformers is not an integer; however, by arranging windings having the unequal numbers of turns on different sub-transformers, or arranging windings on the sub-transformers in a layered manner, the actual total number of turns of the high-voltage side winding matches the designed number of turns, and then there is no need to sacrifice the efficiency and the voltage regulating range of the matrix transformer. Under a condition that the numbers of turns of the second windings of the n sub-transformers are equal, voltages corresponding to the second windings are equal, so that the second windings can be used directly in parallel. Therefore, the normal use performance of the matrix transformer is ensured.
