Beschreibung
Zusammenfassung:	The invention provides high-power power supply equipment, which comprises a rectification circuit, a direct current reactor and a surge absorption apparatus, wherein the rectification circuit is used for converting alternating current into direct current; the direct current reactor is connected to a direct current side of the rectification circuit in series and used for improving current waveform; the surge absorption apparatus is coupled to two ends of the direct current reactor and connected with the direct current reactor in parallel; and when the direct current reactor generates an induced voltage opposite to the flow direction of the current on the direct current side of the rectification circuit due to surges on the direct current side of the rectification circuit, the surge absorption apparatus is started to clamp the induced voltage generated by the direct current reactor in a safe voltage range. According to the high-power power supply equipment, the surge absorption apparatus is adopted to clamp the
