Sliding-mode control for boost converters under voltage and load variations

<p><span lang="EN-US">Boost converters are employed in DC motors, switch-mode power supplies, and other applications. Practical implementation difficulties, reliance on variable-frequency units, delayed dynamic responses to changes load voltage the main drawbacks of different control methods for boost converter. In this paper, two techniques were proposed with target controlling converter improve efficiency converter's performance. The used paper depended fixed-frequency mode instead because demerits latter factor. first technique is sliding-mode AC-DC achieve factor correction reduce harmonic ratio significantly while regulating output voltage. This was DC-DC obtain a rapid response sudden or considerable loads input voltages regulated Moreover, two-loop cascade second an excellent under step variations excellently Re-simulation results validated design approach illustrated controller's robustness faster time.</span></p>
