Abstract

Quasi-Z Source indirect matrix converter (QZS-IMC) has been proved to have abilities of voltage boost, current filtering, variable voltage and variable frequency. The voltage gain of QZS-IMC depends on QZS network shoot-through duty ratio D, rectifier modulation ratio mi, and inverter modulation ratio mo. Their multiple combinations are able to achieve the same voltage gain, whereas which is the optimal has not been addressed. In addition, the size of D is associated with the duration of shoot-through events of QZS network, voltage and current stresses of power devices, and the system power losses. This paper proposes to find the optimal operation curve of D based on constrained optimization theory. Simulation and experimental results validate theoretical analysis, the proposed optimal control, and the power loss reduction of the QZS-IMC.
