Space voltage vector PWM control of three-level rectifiers based on single neuron

The principle of space voltage vector pulse width modulation (PWM) of three-level rectifiers was described. The control structure of three-level rectifiers was presented. A current controller based on single neuron was designed. Computer simulation results indicate that the three-level rectifiers with single neuron controller has ideal output current and voltage in the case of varying load and nonlinear load. If the condition of the reference value of reactive current changes, the current in the power network still has ideal output. The current controller with single neuron is easy to be implemented and shows a good application prospect.
