DC-DC interleaved boost converter using FPGA

This paper presents the design of dc to dc Interleaved Boost Converter (IBC) which is controlled using Field Programmable Gate Array (FPGA). The output voltage can be controlled by Pulse Width Modulation (PWM) switching technique which is implemented on the Altera DE2-70 Board. An eight bit Analog to Digital Converter circuit is used to monitor the output current. The simulation is carried out using Matlab Simulink software and simulation on the designed waveform is conducted using Quartus II software tools. The frequency of the PWM output voltage is set to 40 kHz. Various detailed analysis has been done to investigate the benefits of IBC compared to conventional boost converter. Meanwhile, theoretical analysis and hardware prototype has been done to validate the result.
