The circuit is as shown in figure 2-15. When L2 is in the positive half cycle, VD charges the GB; when L2 is in the negative half cycle, GB discharges, the voltage of GB and L2 are superimposed to charge C. When the positive half cycle comes again, the C discharges to charge the GB, so the power which is released by GB is utilized. When C is discharged, VD conducts to charge the GB. So repeatedly, the GB is fully charged. You can control the discharging of GB by change the capacity of C. The LED can be used in the working indication.
