Split type six-phase motor control system integrated with alternating current charging and method thereof

Abstract

The invention discloses a split type six-phase motor control system integrated with alternating current charging. The system comprises a main control module, a driving module, a direct current module,a pre-charging module, an inversion unit module, a split type six-phase motor and a PFC inductance module connected to an alternating current socket. An alternating current charging port and a splittype six-phase motor port of the inversion unit module drive alternating current to input voltage signals to control a six-phase motor, and the inversion unit module is electrically connected with thealternating current socket through the PFC inductance module. According to the control method disclosed by the invention, a quick charging method of the alternating-current charging is adopted, and quick electric quantity input of the six-phase motor is realized through shunting and converging control of the inversion unit, so that the purpose of quick charging of the electric automobile is achieved.

Description

technical field [0001] The invention belongs to the field of electric vehicles, and more specifically, the invention relates to a split six-phase motor control system integrated with AC charging and a method thereof. Background technique [0002] With the development of modern science and technology, the increasingly serious environmental problems have gradually attracted people's attention, and how to better protect the environment while developing science and technology is particularly important. Green and environmentally friendly new energy vehicles have become the main focus of the future development of the automotive industry. At present, my country has comprehensively promoted the strategic development of new energy vehicles. The electric motor has replaced the traditional fuel engine as the core device of the automobile drive system. Discrete devices are used to control the motor in parallel, but how to solve the stability and charging of the device in the actual applic...

Problems solved by technology

[0003] The mainstream charging solutions in the prior art are DC fast charging and single-phase AC charging. DC fast charging has high investment cost and large volume, and does not take advantage of the current rapid development of new energy vehicles; single-phase AC charging takes a long time, and there are other Some special vehicles, such as sanitation top-loading vehicles or dual-motor drive vehicles, need to design two controllers and motors, which makes the overall system of the vehicle complex, reduces system reliability, increases costs, and uses a large number of discrete devices in parallel. , it is difficult to troubleshoot the problem, how to realize the current sharing of discrete devices, improve the reliability of discrete devices and reduce the charging time is also a key problem to be solved at present
