Under the background of global energy conservation and emission reduction, the motor control field has increasingly higher requirements for improving the system efficiency on the premise of meeting the requirements of normal functional performance. Particularly, in the increasingly popular electric automobile, high efficiency and low cost are required for an automobile main drive system, and space volume is required to be reduced as much as possible so as to meet better user space experience. Under the background, the importance of electric automobile manufacturers on high conversion efficiency, high power density, high integration and low cost of high-voltage driving systems is increasing, so that upstream component manufacturers are required to timely push out schemes with higher power density, lower cost and higher integration.
However, the current known research institutions focus on the innovative design of the circuit system, and neglect the influence of the additional loop loss and the noise caused by the combination of the discrete switching devices in the system application, the influence will possibly offset the efficiency point raised by the innovation of the control scheme, and the complexity of the system structure is greatly increased.
In the aspect of a motor driving system, the main methods for improving efficiency mainly comprise the following two methods:
1) And the whole vehicle system is in the highest efficiency interval from the low rotation speed to the high rotation speed according to the combination of different efficiency intervals of the motor by using double motor driving.
2) The use of higher conversion efficiency power conversion devices, such as silicon carbide modules in inverters, reduces the energy loss due to the power conversion process at equal power conditions.
In addition, the system efficiency under different rotation speed conditions can also be controlled by controlling the number of turns of the motor winding connected to the main circuit.
The three-phase winding turns ratio can be controlled in various ways, one switching device is formed by dividing a motor winding group into two or more sections, and a set of switching control devices are respectively connected to different positions of the three-phase winding, and the switching device mainly provides a through-current circuit for connecting or disconnecting the winding turns in the motor. When the automobile runs at a low speed, a large torque is required, and the more the number of turns of the coil in the switching device is, the more beneficial to the lifting torque is, while when the automobile runs at a high speed, the number of turns of the coil can be properly reduced, so that the motor efficiency is improved through adjustment. When the motor runs from low speed to high speed, the conduction loop is switched between different motor windings step by step, so that the motor can run efficiently in the whole range from low speed region to high speed region.
However, when the double-motor driving scheme is adopted, the control complexity is increased, and a set of motor electric control device is needed to be added on the basis of the existing single motor electric control, so that the system cost and the space required by the system are increased; while the silicon carbide scheme can increase the system efficiency and the power density, the system cost is obviously increased due to the defects of low yield, high design requirement and the like during the silicon carbide period, and a great deal of study and study are still needed in the control of the silicon carbide device.
The method of controlling the turns ratio of the three-phase winding provides a new solution, but the currently known research institutions focus attention on the innovative design of the circuit system, and neglect the influence of the extra loop loss and the noise caused by the combination of discrete switching devices in the system application on the system, the influence possibly counteracts the efficiency point promoted by the innovation of the control scheme, and the complexity of the system structure is greatly increased.

Specifically, the first output terminal U of the three-phase ac circuit is connected to the anode of the first diode D1 and the cathode of the second diode D2, the second output terminal of the three-phase ac circuit is connected to the anode of the third diode D3 and the cathode of the fourth diode D4, and the third output terminal W of the three-phase ac circuit is connected to the anode of the fifth diode D5 and the cathode of the sixth diode D6.
As an example, the single tube module 102 may include: thyristors, insulated Gate Bipolar Transistors (IGBTs) or Metal-Oxide-semiconductor field effect transistors (MOSFETs).
As an example, with continued reference to fig. 1-4, the single tube module 102 includes a control end, a first end, and a second end; the first end of the single tube module 102 is connected with the cathode of the first diode D1, the cathode of the third diode D3 and the cathode of the fifth diode D5; the second end of the single tube module 102 is connected to the anode of the second diode D2, the anode of the fourth diode D4 and the anode of the sixth diode D6.
As an example, referring to fig. 1 to 4, a three-phase interface (interface U, interface V, and interface W), a first outgoing line interface dc+ and a second outgoing line interface DC-; the heat dissipation substrate 105 is provided with a first control signal terminal K1 and a second control signal terminal K2; the three-phase interfaces are respectively connected between the first diode D1 and the second diode D2, between the third diode D3 and the fourth diode D4 and between the fifth diode D5 and the sixth diode D6; the first outgoing line interface DC+ is connected with the first end of the single tube module 102, the cathode of the first diode D1, the cathode of the third diode D3 and the cathode of the fifth diode D5; the second outgoing line interface DC-is connected with the second end of the single tube module 102, the anode of the second diode D2, the anode of the fourth diode D4 and the anode of the sixth diode D6; the first control signal terminal K1 is connected to the control end of the single tube module 102, and the second control signal terminal K2 is connected to the second end of the single tube module 102.

More specifically, the signal acquisition terminal is connected to the signal acquisition module 103 using other connectors 108 (i.e., different from the connectors 108 that connect the single tube module 102).
As an example, the rectifying module 101 and the single-tube module 102 in the chip 100 are each connected with a corresponding connector 108 or a corresponding bus bar 110 using a connection wire 109.
