Three-phase charging inverter

Is a three-phase battery charger integrated with the propulsion system?

This paper presents a new three-phase battery charger integrated with the propulsion system of an electric vehicle. The propulsion system consists of a dual-inverter topology connected to an induction motor via open windings. The electrical vehicles (EV) batteries are divided by two inverters.

Can a multiphase motor be charged with an integrated charger?

Integrated chargers have also been proposed for multiphase motors. These chargers have the advantage of avoiding the problem of torque generation in the propulsion motor that exists in systems that use three-phase motors and Boost rectifiers. So, solutions for five, six, and nine machine phases have been proposed [26, 27, 28, 29, 30, 31].

Which type of charger is used in a multiphase motor?

Due to the converter type, in charging mode, the motor is used as a coupled DC inductor. Integrated chargers have also been proposed for multiphase motors. These chargers have the advantage of avoiding the problem of torque generation in the propulsion motor that exists in systems that use three-phase motors and Boost rectifiers.

What is the proposed EV charger configuration?

The proposed charger configuration is based on a three-phase high power factor current source rectifier. The motor windings are part of the charger since they will operate as a DC inductor. A fast and robust control system for the proposed EV charger will also be presented.
