1. Overview of high-frequency pulse power supply.
High-frequency pulse power supply is a device that converts direct current energy into high-frequency pulse electric energy, which is often used in electroplating, welding, metal melting and other fields. Compared with traditional power supplies, high-frequency pulse power supplies have higher power density and higher energy conversion efficiency. At the same time, because its output current is in the form of pulses, it can effectively reduce the harmonic interference to the power grid.
Second, the basic principle of high-frequency pulse power supply.
The basic principle of high-frequency pulse power supply is to convert direct current into high-frequency pulsed electrical energy by using the energy storage characteristics of the magnetic core and capacitor. When the power is turned on, the core and capacitor start charging, and when the charge reaches a certain level, the energy between the core and the capacitor is converted, and the core releases energy to produce a high-frequency impulse voltage. This process is repeated over and over again, resulting in a continuous high-frequency pulse current.
