Microgrid is an interconnection of renewable energy sources, loads, power electronic interfaces and energy storage devices. Renewable energy sources are intermittent in nature, and therefore, there is a need for energy storage devices to ensure continuous power supply to the load. Power electronic converters are required to interface the DC bus with energy storage devices. In this work, a bidirectional interleaved switched capacitor DC–DC converter is proposed as a power electronic interface for microgrids. The renewable energy source supplies energy to the load and charges the energy storage device when it is available. The stored energy in the energy storage device supplies energy to the load when the renewable energy source is not available. This is achieved by the proposed converter as it operates bidirectionally. The interleaving technique is carried out at the input side of the converter which reduces the input current ripples. The proposed converter has the following advantages: (i) reduction of ripple current, (ii) reduced voltage stress and (iii) extensive voltage gain and efficiency. It operates in both boost (step-up) and buck (step-down) mode. A 3 kW solar-powered microgrid with bidirectional interleaved switched capacitor DC–DC converter is designed and simulated in MATLAB. The simulation results are associated with the theoretical results obtained from MATLAB. |
