Summary:
First, the main circuit
The whole process of input and DC output from the AC grid includes: 1. Input filter: Its function is to filter the clutter existing in the grid, and also hinder the clutter generated by the machine from being fed back to the public grid. 2. Rectification and filtering: The AC power supply of the power grid is directly rectified into a smoother DC power for the next level of transformation. 3. Inverter: The rectified DC power is changed into high frequency AC power, which is the core part of the high frequency switching power supply. The higher the frequency, the smaller the ratio of volume, weight and output power. 4. Output rectification and filtering: Provide stable and reliable DC power supply according to load requirements.
Second, the control circuit
On the one hand, sampling from the output, comparing with the set standard, then controlling the inverter, changing its frequency or pulse width to achieve output stability, on the other hand, according to the data provided by the test circuit, identified by the protection circuit, provided The control circuit performs various protection measures on the whole machine.
Third, the detection circuit
In addition to providing various parameters in the protection circuit, various display instrument data are also provided.
Fourth, auxiliary power supply
Provides different power requirements for all single circuits. Switch control voltage regulation principle
