Abstract:
A power supply circuit can include: a constant current control circuit configured to receive a first voltage and a first current from a power supply, and to generate a second voltage and a second current that are substantially constant; a shunt circuit, where when the second current is greater than the output current, the shunt current circuit is configured to shunt the second current, and when the second current is less than or equal to the output current, the shunt circuit stops operating; and an energy storage circuit, where when the second current is greater than the output current, the energy storage circuit is configured to store energy, and when the second current is less than or equal to the output current, the energy storage circuit is configured to release energy and provide power for the load together with the constant current control circuit.

Claim (Index 10):
The power supply circuit of  claim 9 , wherein the constant voltage control circuit comprises:\n a) a second transistor having a first terminal coupled to the first terminal of the energy storage circuit, and a second terminal connected to an input terminal of the load; b) a second resistor coupled between the first terminal and a control terminal of the second transistor, and being configured to drive the second transistor; c) a second comparator having a non-inverting input terminal coupled to a positive pole of the second voltage source, an inverting input terminal configured to receive the output voltage, and being configured to output a second comparison signal, wherein a negative pole of the second voltage source is connected to the ground; and d) a second switch controlled by the second comparison signal, and being coupled in series between the control terminal of the second transistor and the ground.
