| Abstract: | Abstract: A two-stage DC/DC converter of Boost cascaded topology is presented in this paper to satisfy low input voltage, high input current, low input current ripple and high-gain requirements of energy feedback electronic load system. The first stage is interleaved boost converter which meets the high input current requirement and reduces the input current ripple, and two cascaded stages can achieve high-gain easily. The analysis of the operation theory and design process of input current loop are presented. The fixed input current control and equilibrium of interleaved boost inductance currents are implemented based on DSP. Finally, a 3.3V-input 48V-output 330W prototype is built. Experiment results meet the requirements of energy feedback electronic load system and verify the theoretical analysis. |
