For the mathematical model of PWM inverter under the d-q rotary coordinate system, there exists coupling between the active current and reactive current, which makes it difficult manipulating the power injected into AC grid from distributed generation system. So as to handle the problem, a novel current decoupling strategy based on the input-output linearization is employed in the paper and the PI...
The Selective Harmonic Elimination (SHE) PWM technique has become a significant PWM method for less switching loss for three-level neutral-point-clamped (NPC) inverter. This paper introduces an online optimization approach to the SHEPWM technology based on genetic algorithm and BP neural network. The method doesnpsilat need to preset the initial values and to predict the trend of these values over...
On the basis of analyzing three-level inverter direct torque control principle (DTC) , a new synthesizing vectors PWM method of three-level DTC is presented, which can not only effectively control neutral- point voltage, but also restrain higher dv / dt of output voltage and improve three-level DTC output performance ,reduce torque ripple. Through theory analysis and experiment research, the author...
