Abstract
The present invention provides a kind of Picking and Supplying Circuit for Discharging Direct Current, which is connected with supplying line of alternating current of electrical loading in series. It contains a picking part with a control triac under a closing state, for picking the alternating current of specified volume; a commutation and voltage regulating loop, which has two pairs of diodes connected reversely in series each other, and one diode with certain voltage is connected between a pair of diodes connected in series for commutating the picked alternating current and regulating voltage and discharging the direct current; a trigger loop was designed for connecting commutation and voltage regulating loop and providing a reverse sign to make the control triac convert into an unobstructed state from the closing one and making the alternating current reply and recover the supply of the electrical loading.
