Problems solved by technology

[0004] However, limited by circuit specification and topology design, the power conversion efficiency of the auxiliary power circuit is generally lower than the power conversion efficiency of the main power circuit. As a result, the power supply device will generate too much inefficiency. Power is not conducive to energy saving

Embodiment Construction

[0062] The present invention proposes a power supply device and a power supply method thereof. The power supply device can judge whether the main power circuit is in a normal operation state according to the voltage difference between the main power supply and the auxiliary power supply, and the main power supply circuit is in a normal operation state. In this case, the power supply source of the auxiliary power supply load is switched to the main power provided by the main power supply circuit, so that the power conversion efficiency of the overall power supply device can be improved. In order to make the content disclosed in the present invention clearer and clearer, specific embodiments are taken as examples to describe in detail below. In addition, components / members / steps with the same reference numerals in the drawings and the implementations represent the same or similar components.

Abstract

An apparatus and a method for power supply are provided. The apparatus for power supply includes a main power circuit, an auxiliary power circuit and a power switching control circuit. The main power circuit is configured to generate a main power suitable to be provided to a first load and a second load for use. The auxiliary power circuit is configured to generate an auxiliary power suitable to be provided to the second load for use. The power switching control circuit is configured to detect a voltage difference between the main power and the auxiliary power and determine whether the apparatus meets a normal power supply condition, so as to select one of the main power and auxiliary power as a power source of the second load.

Description

technical field [0001] The present invention relates to the technical field of power supply, and in particular to a power supply device having a power supply structure of a main power circuit and an auxiliary power circuit and a power supply method thereof. Background technique [0002] When the use of electronic devices increases, the power consumption will also increase. In this regard, in order to solve the power consumption of electronic devices and effective power management, a technology called Advanced Configuration and Power Interface (Advanced Configuration and Power Interface) The power management mechanism of the Advanced Configuration and Power Interface (ACPI) specification has been used to manage the power of the electronic device, and the state of the entire electronic device will be classified into six different types based on the power management mechanism of the Advanced Configuration and Power Interface (ACPI) specification Status of power consumption (S0 ...
