The electronic circuit simulation technology mainly refers to the electronic designer using a computer to graphically or digitally display the working state of the electronic circuit. The electronic circuit simulation technology can fully reflect the actual working condition of the electronic circuit, and the designer can easily analyze the circuit function and circuit characteristics by using this technology. In general, electronic circuit simulation technology is mainly expressed by mathematical models of electronic devices and circuit modules, and then through accurate numerical analysis, finally accurately grasp the actual working state of the circuit, circuit simulation technology Applications drive electronic application development.

In recent years, with the continuous advancement of science and technology, various electronic products have emerged in an endless stream, bringing great convenience to people's life and work, greatly improving the efficiency of human society, and upgrading electronic products. faster and faster. A more mature electronic product has a market life expectancy of only half a year. In order to adapt to the needs of the market and keep up with the pace of upgrading electronic products, the development of electronic applications has also undergone tremendous changes.

The development direction of modern electronic technology is the traditional power electronics, which is mainly based on the processing of low-frequency technology, and the modern power electronics, which is mainly based on high-frequency technology. Advanced computer technology has led humans into the information society and has also promoted the rapid development of power technology. In the 1980s, the computer was fully equipped with a switching power supply to complete the computer power generation. Then switching power supply technology has entered the field of electronics and electrical equipment. In the application of power electronics technology and various power systems, switching power supply technology is at the core. By adopting high-frequency switching power supply technology, the volume and weight will be greatly reduced, and the power utilization rate can be greatly improved, and materials can be saved to reduce costs.
