چکیده
---------------------------------------------------------------------***--------------------------------------------------------------------Abstract One of the main disadvantages of the buck converter and the interleaved buck converter is the narrow duty cycle which limits the application of the converters for high step-down applications. The interleaved buck converter with high conversion ratio overcomes this drawback. This converter provides continuous input current and also reduces the voltage stress of the semi-conductor devices to below the input voltage. This is possible due to the presence of two input capacitors. Also, compared to the conventional interleaved buck converter the converter provides much lower output current ripple. The simulation of the circuit with 200 V input, 24V/10A output is done using MATLAB. One-cycle control is used to generate the gate pulses.
