Half-bridge Transformer Optimizing Design Based on Finite Element Simulation
摘要
Abstract
As the important part of switching power supply ,transformer design will directly affect the circuit perform‐ance like normal working performance ,anti‐electromagnetic interference performance and circuit efficiency .So how to design the transformer reasonably to meet the performance optimization has become the focus of the study .The half‐bridge trans‐former with high utilization rate of the core and without magnetic bias and DC magnetic saturation need not add an air gap , which has strong ability of anti‐imbalance to prevent the occurrence of bias effectively .So the half‐bridge transformer is widely used in the high‐power switching power supply and its design is extremely critical .Based on the analysis on the work‐ing principle of half‐bridge converter ,Ansoft's finite element simulation software was used to optimize the design of the half‐bridge transformer respectively from the two aspects of the energy density distribution and the temperature field distribution , and the model diagram of the transformer was obtained .Finally ,the leakage inductance is analyzed ,and the methods to re‐duce the leakage inductance were given out .关键词
