This paper presents experimental results of a sensorless control strategy for PWM rectifiers with active filtering function. The proposed technique, already presented for PWM rectifiers, has the capability to reject harmonic components from the grid, and can be employed for harmonic mitigation of shunt connected load. The mitigation of harmonics of the current shaping control is improved with a multiple...
This paper presents a control strategy for pulsewidth-modulation rectifiers without grid voltage sensors employing a current-shaping strategy. The proposed technique has the ability to reject harmonic components from grid voltage and power factor adaptation in the presence of uncertain grid impedance. The harmonic compensation is selective, obtained from multiple resonant modes tuned in the desired...
This paper presents a sensorless control strategy for shunt power active filter. The proposed technique, already presented for PWM rectifiers, has the capability to reject harmonic components from the load and grid. An adaptive algorithm is employed to achieve a high power factor in the grid even for uncertain parameters of the circuit impedance and load power. A selective harmonic compensation is...
