Beschreibung
Zusammenfassung:	The invention relates to a single-phase vehicle-mounted integrated three-level NPC charging power supply module which is formed by cascading a single-phase alternating current power supply unit, a three-phase permanent magnet synchronous motor, a three-level NPC converter and an energy storage type direct current storage battery in sequence. The single-phase AC power supply unit is composed of a power grid, a charging switch K1 and a discharging switch K2. The power grid is connected with K1 in series and then connected with K2 in parallel. One end of the single-phase alternating-current power supply unit, the direct-current storage battery and a two-phase inductor of a stator of the three-phase permanent magnet synchronous motor are connected with the three-level NPC converter, and the other end of the single-phase alternating-current power supply unit is connected with another phase inductor of the stator; a three-phase inductor of the three-phase permanent magnet synchronous motor rectifies alternating cur
