| Abstract: | A kind of PSFB ZVS DC/DC converter topology with clamping diode is presented and the parasitic oscillation on traditional PSFB ZVS PWM DC/DC converter bridge rectifiers is also solved.The structure of main circuit and operation principle of converter are demonstrated.The voltage ring with current limiting protection and current limiting control system is designed,using TMS320LF2407A as MPU.The two closed loop digital control on converter system is realized.After the experiment,the wave is given and it proves the correctness of circuit design and control system. |
