Abstract
Aiming at the problem that the traditional matrix converter's voltage transmission ratio is lower than 0.866, which limits the application of matrix converter, a quasi-Z-source indirect matrix converter topology is proposed based on the concept of quasi-Z-source network voltage boost. The quasi-Z-source indirect matrix converter combined the traditional indirect matrix converter and quasi-Z-source network can improve the voltage conversion rate, but the actual voltage boost effect is not ideal, due to the limitation of duty ratio and modulation coefficient. The proposed quasi-Z-source indirect matrix converter topology combined two quasi-Z-source networks with the indirect matrix converter, which can reduce the influence of duty ratio and modulation coefficient, and increase the voltage transmission gain by 3～4 times. The voltage transmission ratio formula of the proposed structure was obtained through formula derivation, and compared with the traditional quasi-Z source indirect matrix converter and indirect matrix converter. Experimental results show that the proposed quasi-Z-source indirect matrix converter topology has higher output gain than the two traditional topologies, which verifies the correctness and effectiveness of the proposed topology.
