Research on Three-Level Mining Inverter Based on SVPWM
The frequency conversion speed regulation of household inverter is the key to guarantee the normal operation of household electrical appliances preparation,and its performance directly affects the safety and efficiency of electrical appliances in use.In order to improve the speed regulation performance of household inverter and enhance the stability of household electrical appliances,SVPWM modulation is proposed on the basis of two-level commonly used inverter technology with PWM control,and three-level topology is adopted,and then the simulation model is built by using matlab-simulink,and the results show that:the output voltage and current waveforms of three-level household inverter based on SVPWM are very close to sinusoidal waveforms,which can control the motor more smoothly and improve the efficiency and efficiency of household electrical appliances.close to sinusoidal waveforms,which can control the motor more smoothly and improve the efficiency and performance of household appliances,as well as save energy and reduce equipment noise.
