Chopping switching stabilized voltage supply is DC energy supply. It can get single-direction square wave after passing switching circuit. Then it can get stable DC which is different with input voltage after filtering. Soit means that whether input voltage Ui is positive or negative, output voltage Uo is always lower than input voltage Ui, that is | Uo|≤|Ui|. The diagram shows reduced voltage chopping type switching stabilized voltage supply principle diagram. When switching component VT is controlled and saturation conduction, the energy is stored in inductor L and capacitor C. When switching component T is controlled and in the cut-off state, the energy stored in inductor and capacitor is still offered to load, and the diode CD makes up the current loop. It is also called series switching stabilized voltage supply because switching component VT and load resistor RLare connected inseries.
