Abstract

A power supply device, a circuit control method and a power supply system, belonging to the field of power supply conversion technologies. The power supply device can ensure that a second-stage conversion circuit has a sufficiently high valley voltage by means of a valley-fill circuit without using an electrolytic capacitor or other large-volume capacitors, thereby ensuring that the output voltage of the power supply device is overall stable. On the other hand, the power supply device can, by controlling the voltage of an energy storage unit, utilize the ability of the energy storage unit to store electric energy as far as possible whilst ensuring that the voltage does not exceed a specific voltage, so as to lower the requirements on the voltage resistance of the energy storage unit, thereby realizing the miniaturized design of the power supply device and improving the portability of the power supply device.
