| Abstract: | LCC load-resonant topology is researched to realize switching power supply by soft-switching,and an in-depth discussion referring the work principle,work processes,system characteristics between input and output and ap-plication method is provided based on LCC load-resonant DC/DC power supply.The impact of the resonant circuit pa-rameters on the converter characteristic is discussed,and the prototype parameters are designed.Closed-loop control system is designed based on DSP.The simulation and experimental results certify the effectiveness of the soft-switch-ing power supply based on LCC topology and the design method. |
