A novel design and implementation of frequency superposition testing power supply for induction motor is proposed. An equivalent power using dynamic space voltage vector synthesis is generated to replace the two separate powers of the traditional method. The principle of frequency superposition testing is firstly introduced, and then the detailed design and implementation of the digital frequency superposition power are given. The simulation of the power supply system shows the promising results. Finally, experimental results validate the feasibility and reliability of the proposed power.
