Tips: Switching power supply development
The development of switching power supply is high-frequency, high reliability, low consumption, low noise, anti-interference and modularity. The performance of switching power supply in light weight, small size and thickness depends on its high frequency. Upgrading of secondary rectification devices and innovation of power ferrites have improved its magnetic performance in high frequency and field density conditions. In addition, miniaturization of capacitors also serves as a key technology. Extensive use of SMT technology accelerated development of switching power supply. To ensure outstanding performance of witching power supply in weight, size and thickness, electric components are laid out on both sides of the circuit. High frequency of switching power supply requires innovation of PWM. As a result, ZVS and ZCS have been applied to switching power supply as supporting technologies to improve its efficiency.
