Closed loop CLL type AC/DC converter using ORCAD PSPICE

The closed loop CLL type converter system does AC/DC conversion with high power density. This is possible by using smaller size filters. Low frequency AC is converted into DC an using uncontrolled rectifier. This DC is converted into high frequency AC using MOSFET inverter. The filter size is reduced since the MOSFET inverter operates at high frequency. This AC is converted into DC by using a rectifier at the output. The size of the capacitor filter will be reduced since the ripple frequency is very high. The waveforms are simulated using PSPICE. The harmonics are studied using Fourier transform. This converter is used for defence power supplies and aircraft power supplies.
