8. A multidimensional space vector modulation (MDSVM) system, comprising:
a circuit carrier including a multidimensional space vector modulation circuit, wherein the circuit carrier comprises:
N electronic components, N is a positive integer not less than 3, first end of each of the N electronic components being coupled to each other to form a neutral point, wherein the N electronic components are configured to generate N magnetic fields; and
N+1 logic control circuits connecting with each other in parallel, each of the N+1 logic control circuits having at least two switches coupled to each other in series, wherein the neutral point is directly connected between the at least two switches of one logic control circuit of the N+1 logic control circuits, and a second end of each of the N electronic components is respectively coupled between the at least two switches of other N logic control circuits of the N+1 logic control circuits than the one logic control circuit directly connected with the neutral point, and no electronic component is directly connected between the neutral point and the one logic control circuit;
a power supply coupled to the circuit carrier; and
a controller coupled to the multidimensional space vector modulation circuit for transmitting electronic signals to the N+1 logic control circuits to control switching states of the at least two switches of the N+1 logic control circuits, thereby controlling a voltage difference between the first and second ends of the N electronic components,
wherein strengths and directions of the N magnetic fields generated by the N electronic components are adjustable by the at least two switches of the N+1 logic control circuits, and the MDSVM system is configured to supply power to a multi-degree-of-freedom (Multiple DOFs) motor.
