Abstract：How to gain a safe commutation is the key problem that restricts the practical application of matrix converter (MC), and when MC and high frequency link are combined together it becomes more complex for the high frequency transformer. The commutation of three-phase inverter based on high frequency linked matrix converter (HFLMC) is taken as focus in the study. According to the character of the converter’s topology De-Re-couple idea is used to analysis and control the MC by way of classical inverter designing. A novel no resonant hybrid pulse width modulation (HPWM) strategy is proposed, and the key logic for this strategy is also contructed. The operating modes within a high frequency transformer AC period of the converter are shown with close analysis. The HPWM can efficiently solve the inherent commutation problems of AC switches in the converter based on HFMC. The AC switches can gain zero voltage switching (ZVS) or zero current switching (ZCS) under the control of the strategy. Simulation and experimental results show that the HPWM strategy and the dedicated logic are feasible and practicable.
