| Abstract: | A novel controller based on K60 MCU and FPGA is proposed which is applied to four-phase interleaved Boost converter.The number of the converter can be changed automatically with the output current detected,which can improve the efficiency of the converter.The digital PID control algorithm is used to regulate the output voltage without error and improve the response speed of regulating voltage when the load changing.Also,voltage/current sampling circuit,MOSFET driver circuit,memory circuit and software control algorithm are designed.A four-phase interleaved Boost converter prototype is built to verify the design''s correctness. |
