Abstract :
A new current controller adopting dual hysteresis loops for a high-performance four-switch boost rectifier is proposed in this paper. The four-switch boost rectifier is operated under the so-called phase-adjusted unipolar PWM strategy. The inner loop confines the current ripple within a preset band. The outer loop determines the instants to change the switching patterns. Experimental results are satisfactory
