DESIGN AND IMPLEMENTATION OF TWO PHASE INTERLEAVED DC-DC BOOST CONVERTER WITH DIGITAL PID CONTROLLER

DC-DC converters are widely used in Industrial, Commercial and Non Renewable energy applications and also especially in Switch Mode Power Supplies. The two phase interleaved DC-DC boost converter (IBC) for low input voltage applications is designed and implemented with digital controller. The interleaved concept is used to meet the increased demands and also a low current ripple in source current due to this reducing the size of the filter component in input and output. Using interleaving concept can reduces stress on the devices, increases in efficiency, faster dynamics, light weight, compactness and higher power density. The digital controller was designed and implemented by using Field Programmable Gate Array (FPGA). The proto type model
