A Space Vector Modulation Without Voltage Spikes for Single-Phase Voltage Source High-Frequency Link Matrix Rectifier

The single-phase high-frequency link matrix converter has been widely used in many fields, most of which are based on voltage sources. A novel space vector modulation for the single-phase voltage source high-frequency link matrix rectifier is proposed in this paper. Through pre-charging the leakage inductance of the transformer, the voltage spike caused by the leakage inductance of the transformer is solved, and the current spike is also suppressed. And the working modes of the circuit topology is analyzed in detail. Finally, the simulation results verify the feasibility and effectiveness of the proposed modulation strategy.
