Abstract :
The features of low voltage high current switch mode power supply in power system applications is improved by raising its dynamic performance, efficiency and reducing input ripple current. Generally a conventional cuk converter in continuous conduction mode brings in large current ripple on input side which in turn injects harmonics to the source. This undesirable input current ripple is mitigated by employing the interleaved cuk converter (ICC). Simulation results of 40V, 80W ICC using Phase Shifted Pulse Width Modulation (PSPWM) technique shows that the input ripple current has been reduced significantly from 7.5A to 0.6A compared to conventional cuk converter.
