Design Optimization Method of High Frequency and High Voltage Transformer Based on Genetic Algorithm

Abstract

The invention discloses a method for optimizing the design of a high-frequency high-voltage transformer based on a genetic algorithm. The invention establishes a mathematical model based on the minimum loss formula of the transformer, the insulation size of the transformer and the shape of the iron core, and takes the number of turns of the primary side and the number of layers of the secondary side as Optimize variables, efficiency is the optimization goal, and genetic algorithm is used to optimize the transformer to maximize the efficiency of the transformer and minimize the loss. Under the same conditions, it also means to minimize the temperature rise, and make full use of the leakage inductance and distributed capacitance of the transformer to participate in the power supply. In the work of the system, the LCC resonant circuit is formed to reduce the loss of the transformer, thereby reducing the temperature rise. Compared with the prior art, the present invention introduces a genetic algorithm, which has a fast and random search capability irrelevant to the problem. The search starts from the group and has the characteristics of parallelism. It can compare multiple individuals at the same time, which greatly speeds up the process. the speed of finding the optimal solution.

Description

technical field [0001] The invention relates to a design method of a high-frequency high-voltage transformer, in particular to a design method of a high-frequency high-voltage transformer for an electrostatic precipitator power supply based on a genetic algorithm. Background technique [0002] With the rapid development of domestic industry, people's lives are becoming more and more convenient, but the ensuing environmental pollution problems are becoming more and more serious, especially the severe smog weather has had a serious impact on our health and travel, the new The establishment of air emission standards has brought new requirements and opportunities to the dust removal industry. High-frequency and high-voltage electrostatic precipitator power supplies are more and more widely used in the dust removal industry, and their performance requirements are also getting higher and higher. [0003] The high-frequency transformer is the core component of the entire electrost...

Problems solved by technology

[0003] The high-frequency transformer is the core component of the entire electrostatic precipitator power supply, but abnormal situations such as high temperature of the transformer and untimely heat dissipation often occur, especially the characteristics of the high-frequency transformer are much different from those of the power frequency transformer with the high frequency of the input. Different, too high temperature will not only affect the insulation life of the transformer, seriously even affect the stable operation of the power grid, and bring unnecessary losses to people's production and life, so the temperature of the high-frequency high-voltage transformer must be controlled within a reasonable range
