Zusammenfassung:The utility model provides an inverter power supply system with an ultra-wide voltage input range. The inverter power supply system comprises a three-phase AC input power supply, a three-phase EMI filter, a three-phase bridge rectifier, a four-switch Buck-Boost module, an H-bridge inversion module, an auxiliary power supply module and a main controller. The three-phase alternating current input power supply, the three-phase EMI filter, the three-phase bridge rectifier, the four-switch Buck-Boost module and the H-bridge inversion module are electrically connected in sequence; the main controller is electrically connected with the three-phase bridge rectifier and the four-switch Buck-Boost module; the auxiliary power supply module is electrically connected with the main controller and the three-phase bridge rectifier. According to the inverter power supply system with the ultra-wide voltage input range provided by the utility model, 60-650V alternating current is converted into direct current through the three-
