The development trend of switching power supply technology is very in-depth analysis of the development trend of switching power supply technology in the future.
1. High frequency, lightweight and miniaturization. For switching power supply, its weight and volume will be affected by energy storage components, such as capacitors and magnetic components. Therefore, in the development trend of miniaturization, it is actually to start from energy storage components and achieve the purpose of switching miniaturization through the reduction of the volume of energy storage components. In the specified range, increasing the switching frequency can not only reduce the size of transformer, inductance and capacitance, but also suppress some interference and make the switching power supply system obtain higher dynamic performance. Therefore, high frequency has become one of the main directions of the future development of switching power supply.
2. High reliability. Compared with the continuous working power supply, the number of components in the switching power supply is relatively large, so its reliability is more vulnerable to relevant factors. For the power supply, its service life usually depends on the components such as exhaust fan, optical coupler and electrolytic capacitor. Therefore, it is necessary to start from the design point of view, try to avoid the number of components in the switching power supply, strengthen the integration of various components, and adopt modular technology, Build a distributed power system, so that the reliability of the system can be effectively improved.
3. Low noise. Excessive noise is one of the main defects of switching power supply. If we simply pursue high frequency, the noise in its use will be greater and greater. Therefore, through the resonant conversion circuit, we can improve the working principle of switching power supply and effectively reduce the noise while increasing the frequency. Therefore, controlling the noise impact of switching power supply is also an important direction of its progress.
4. Low output voltage. We know that semiconductor is the key component of switching power supply. Therefore, semiconductor technology will directly affect the progress of switching power supply technology. For portable electronic devices and microprocessors, whether the working voltage is stable or not will have a certain impact on the use of equipment. Therefore, in the future development, low voltage can be used as the design purpose to design semiconductor devices, So as to improve the working quality of relevant electronic equipment and microprocessor.
5. Digital technology. In the traditional form of switching power supply, analog signal can correctly guide the use of control part, but at the current stage, digital control has gradually become the main way of many equipment control, especially in switching power supply, which is one of the main aspects of the application of digital technology. Relevant staff have carried out in-depth research on digital power supply technology and achieved certain results, This will greatly promote the digital progress of switching power supply technology.
In general, the in-depth exploration of the working principle and development direction of switching power supply can help relevant industries better carry out exploration and innovation, which plays a very positive role in the development of switching power supply industry. Therefore, relevant industries must pay attention to the existing switching power supply technology
