Problems solved by technology

[0004] It is worth noting that when the switches SWA1~SWA4 are switching, the current in the circuit will cause arcing.
Moreover, the bouncing phenomenon during the switching process of the switches SWA1~SWA4 will generate high-frequency noise correspondingly, and affect the operation of itself and surrounding circuits

Embodiment Construction

[0041] Please refer to figure 2 , figure 2 A schematic diagram of a power supply device according to an embodiment of the present invention is shown. The power supply device 200 includes a power switch 210 and a power supply generator 220 . The power switch 210 can be an automatic power switch, and has switches SW1 and SW2. The switch SW1 is coupled to the live line L1, and the switch SW2 is coupled to the live line L2. The power switch 210 receives the power VP1 through the live line L1 and the neutral line N1 , and the power switch 210 receives the power VP2 through the live line L2 and the neutral line N2 . Wherein, the power switcher 210 receives the power VP1 through the switch SW1 to generate the selected power VS1 , or receives the power VP2 through the switch SW2 to generate the selected power VS1 .

[0042] The power supply generator 220 is coupled to the power switch 210 . The power supply generator 220 receives the selected power VS1 , and performs voltage co...

Abstract

A power supply apparatus and a power supplying method thereof are provided. The power supply apparatus includes a power switch and a supplied power generator. The power switch respectively receives afirst power and a second power through a first switch and a second switch. The supplied power generator converts the first power or the second power to generate a supplied power. When the supplied power generator judges the first power being cut off, during a first time period, the first switch is cut off and a voltage converting operation of the supplied power generator is stopped. During a second time period, the second switch is turned on, and the voltage converting operation of the supplied power generator is restarted after the second switch being turned on. The provided power supply device and power supply method thereof can avoid the generation of arc during the power switch process, and bouncing of switches.

Description

technical field [0001] The present invention relates to a power supply device and a power supply method, and in particular to a power supply device and a power supply method for an uninterruptible power supply system. Background technique [0002] In the known technical field, the power supply device of the uninterruptible power system uses an automatic power transfer switch (Automatic Transfer Switch, ATS) to switch between the main power supply and the auxiliary power supply. Please refer to figure 1 The circuit diagram of the automatic power transfer switch shown. The known automatic power switch 100 includes a plurality of switches SWA1 - SWA4 , wherein the switches SWA1 , SWA2 are respectively coupled to the live wires L1 , L2 , and the switches SWA3 , SWA4 are respectively coupled to the neutral wires N1 , N2 . The live wire L1 , the neutral wire N1 and the ground wire FG1 are used to receive the power VP1 , and the live wire L2 , the neutral wire N2 and the ground w...
