A Simple Predictive Pwm Voltage Controlled Technique for Implementation of Single Phase Inverter with Precesion Rectifier
نویسنده
چکیده
A single-phase PWM inverter is presented to alleviate harmonic components of the output voltage and the load current. To keep the output voltage being sinusoidal and to have the high dynamic performances even in the cases of load variations and the partial magnetization in filter inductor, the modified digital predictive controller is designed and implemented on a prototype. The validity of the proposed inverter is verified through experiment. Additionally, low-ripple sinusoidal-current waveforms are generated with almost unity power factor. To assess the proposed inverter, it is compared with the conventional single-phase PWM inverter under the conditions of identical supply dc voltage and switching frequency. Keywords—PWM inverter, predictive control, single phase, load current, output voltage, harmonics
