The diagram is boost chopping type switching stabilized voltage supply principle diagram. When switching component is controlledto besaturation conduction, the current passing inductor to make it store energy. When switching component VT is controlled and in the cut-off state, the energy stored in inductor still offers to load through diode VD, meanwhile it is charging to capacitor C. When load voltage is dropping down, the capacitor is discharging again. At this time, it can get stable voltage which is higher than input voltage. It is also called parallel switching stabilized voltage supply, because switching component VT and load resistor RL is parallel.
