Design and Optimization of T-type Converters Using Genetic Algorithm

Tóm tắt

High efficiency and high power density are becoming increasingly popular in the design requirements of power electronic converters. In this
paper, the design and optimization method of a three-phase T-type converter are discussed. Loss models of the converter are formulated by the
conventional method. The switching frequency, peak flux density, number of turns, number of layers,..., are optimized using genetic algorithm
for minimizing the overall converter loss. Simulation results prove that the loss models are reliable. The optimized converter has improved
performance with a high efficiency of up to 99.47% and a low-temperature rise of fewer than 50 degrees Celsius on both inductors and
semiconductor devices. The utilization of computer-aided design methods also significantly contributes to reducing the workload of designers.
