Title:
POWER SUPPLY CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2022/239536
Kind Code:
A1
Abstract:
According to the present invention, when an AC voltage decreases, the voltage across both terminals of a capacitor increases. This power supply circuit (100) comprises a first input end (11a), a second input end (11b), a capacitor (50), a first diode (51), a second diode (52), and a switch (10). The capacitor has a first end (501) and a second end (502) connected to the second input end (11b). The first diode (51) has a cathode connected to the first end (501) and an anode conductively connected to the first input end (11a). The second diode (52) has a cathode connected to the first end (501) and an anode connected to the second input end (11b). The switch (10) is connected between the second end (502) and the first input end (11a) and switches a non-conductive state and a conductive state to each other.
