| Abstract: | Parallel current mode control method for SR-Buck converter is presented. The new control is derived based on discrete domain and optimized for digital implementation. The digital implementation diagram of the new control algorithm is presented. And an experimental prototype of parallel current mode controlled SR-Buck converter based on FPGA is designed. The experiment results show that parallel current mode control has superior performance compared with peak current mode control under load and input voltage variations. |
