摘要：
A direct current high-voltage power source, a high potential power-extracting apparatus, and a power supply method therefor, comprising a high-voltage input end (A), a low-voltage input end (B), an power-extracting circuit, a power-storage circuit, a flip-flop circuit, and a throttle circuit. The power-extracting circuit comprises a switch circuit and a control circuit connected to the switch circuit. The switch circuit comprises at least two switches connected in series. The control circuit, by controlling the opening/closing of the switches, controls the high-voltage input end (A) to charge the power-storage circuit. The flip-flop circuit is connected to the power-storage circuit and the switch circuit and is used for controlling, by controlling the opening/closing of the switches, the high-voltage input end (A) to stop charging the power-storage circuit when the power-storage circuit is fully charged. The throttle circuit, connected at an input end thereof to the power-storage circuit and at an output end
