description:

The Switching Power Supply circuit of the inverter can be simplified to the circuit model above, and the key elements in the circuit are included. And any complex switching power supply, after removing the branches, will also have the backbone of the above picture. In fact, in the overhaul, it is necessary to have the ability to simplify the complex circuit, and to find out the main lines in the seemingly chaotic circuit stretching. To learn from Kenting's Kenting, there is no overall switching power supply circuit in front of training. Only the veins and veins of each part are oriented—oscillation loop, voltage regulator loop, protection loop and load loop.

The accessory is the design circuit, see the PDF document for details!
