Abstract
In this paper, a four-phase DC-DC interleaved boost converter (IBC) is presented with improved power control performances. A closed loop controller has been designed to control the output voltage and current profile of the IBC. The converter with proposed controller offers an outstanding current sharing activity compared to existing control techniques. Pulse width modulation (PWM) switching technique is applied to control the output voltage of the IBC. The operating frequency of the four-phase DC-DC IBC is set to 20 kHz. The control performance of the four phase DC-DC IBC is analyzed by simulation. The simulation work is done using MATLAB/Simulink environment. The four phase DC- DC IBC with proposed controller shows lower voltage and current ripples which is far better than the converter in open loop mode.
