In order to overcome the shortcomings of low voltage transmission ratio of traditional direct matrix converter (DMC), a new quasi Z-source network is coupled to DMC (new QZS-DMC), and an improved double space vector modulation strategy is adopted. Firstly, this essay analysed the topological structure of the new QZS-DMC, along with a detailed explanation of its operating principle. On this basis, an improved double space vector modulation strategy with direct zero vector is adopted. Finally, a detailed simulation is carried out, and a TMS320F28335 prototype controlled by FPGA and DSP is designed for preliminary experimental verification. By conducting a comparative analysis with traditional quasi Z-source direct matrix converter and traditional direct matrix converter, the feasibility and superiority of the new quasi Z-source topology and control strategy are verified.
