Research on PWM Inverter Based on New Space Vector Selection Mode
Space Vector Pulse Width Modulation (SVPWM) can use the power supply with high efficiency. However, the traditional SVPWM algorithm has the disadvantage of complex calculation. At the same time, the low frequency causes the motor to generate pulsating torque, which has high switching frequency, large power loss and other shortcomings. Aiming at the deficiencies of traditional SVPWM modulation, a new SVPWM algorithm for insertion of zero vector is designed in this review. Under the condition that the waveform quality is guaranteed, the power loss of the switch is reduced and the low frequency is enhanced. And MATLAB simulation is used to simulate and verify the correctness of this method.
