A bidirectional two‐input step‐up DC–DC converter with high gain, continuous input current, and common‐ground for EVs and renewable energy systems

Here, a new two-input step-up DC–DC converter for electric vehicles (EVs) and renewable energy systems (RESs) is proposed. It requires few components provides high voltage gain efficiency. The topology includes two input channels connected to sources based on the “switch-mode coupling” method. Sources supply load via proposed converter. Each source can charge another if it rechargeable. regenerative output side also transmitted rechargeable thanks bidirectional power transferring capability. Current sensitive resources be employed as operates with continuous current. comprises only one main switch located low-voltage side; therefore, exposed low stress readily picked up from rating semiconductors small on-resistance. Thanks this feature, conduction loss decreases considerably. terminals have common ground. This paper demonstrates theory operating principle of topology. Experimental results are presented examined verify For purpose, 48/400 V/1 kW prototype has been designed built. Results confirm its operation.
