Design of a Three-phase Interleaved DC/DC Converter for Energy Storage |
| |
| Abstract: | A three-phase interleaved bidirectional DC/DC converter is proposed in this paper,and this new converter not only has low input and output current ripple,low current stress of switches,two-way flow of energy,but also has the high system effi- ciency advantages.In this paper,the operating principle of the new bidirectional DC/DC converter and control strategy is analyzed and the expressions of converter duty and converter duty inductor current are deduced.Finally,a Simulink model and a 20kW prototype converter is built to verify the theoretical analysis. |
