Abstract: The three-phase H-bridge voltage inverter was taken as the research object. The space vector pulse width modulation (SVPWM) strategy commonly used in the field of frequency conversion speed regulation was introduced. The modulation principle of the two-level SVPWM strategy was analyzed,and the modulation process was calculated. The simulation model was built based on Simulink platform for simulation and experimental verification. The simulation and experimental results show the correctness and effectiveness of the two-level SVPWM modulation strategy.

Key words: space vector pulse width modulation (SVPWM), , magnetic chain, , inverter
