Abstract

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 current of a power grid Ug into direct current and transmits the direct current to the direct current storage battery together with the three-level NPC converter in a charging state that K1 is closed and K2 is disconnected; the three-phase inductor corrects a power factor in a charging state and controls input current double-channel staggered circulation, so that input current ripples are inhibited. The module can efficiently and conveniently charge the electric automobile, and is simple in circuit, low in cost and small in size.

Description

technical field [0001] The invention belongs to the technical field of power electronics, and in particular relates to a single-phase vehicle-mounted integrated three-level NPC charging power supply module. Background technique [0002] Rectifier is an important part of power electronic device. Its main function is to use power semiconductor devices to convert AC power into DC power. It is widely used in many fields such as household appliances and industrial equipment. [0003] With the deteriorating climatic conditions, protecting the environment and reducing carbon dioxide emissions has become an important task for all countries in the world; there are hundreds of millions of fuel vehicles in the world, which consume a lot of gasoline every year, so the transition from fuel vehicles to electric vehicles has become a The trend of the automobile industry, electric vehicles only need to use electric energy to drive the car without burning fossil energy, which is very suitabl...
