After developing many years,anolog controller used on the field of inverters is very nature,but is also have many disadvantages With develoPmeni of iniegrated system and digital control,the power eleetronic circuits developed in the direetion of higher frequency and lower constunption. FPGA is a new type of high iniegrated cireuit appeared in recent years.It is economy,high speed,low consumption and easy to be developed and be maintained.At present,FPGA is a research hot spot in power electronic ceircuits control field for its faster speed,higher iniegratedand higher versatility ineomparison with MCU and DSP. Based on the above-mentioned advantages,this Paper studied the digital coniroller of power suPPly based on EP1C3T144 First of all, A more detailed analysis of the various modules of the power controller and the current more popular several control methods .On this basis, the leading edge modulation is selected based on the DPV-PC control algorithm of digital control scheme ,and achieved the control system on Cyelone EP1C3T144.All are designed using VerilogHDL language,to be completed and simulated in Quartusll.,Simulation results show that to improve the control performance.
