Summary: | This article proposes an interleaved, highly efficient, high-gain modified boost converter. High-gain and transformerless converter operation makes the converter suitable for integrating photovoltaic (PV) power to standalone dc microgrid. A coupled inductor is used with two diodes and one switch per phase with a common clamping capacitor to modify the conventional boost converter. The common clamping capacitor and the coupled inductor reduce the converter's component count and size; thus, high efficiency is achieved at a low cost. The proposed converter achieves a high step-up gain and low voltage stress on switches. Interleaved converters are deemed ideal for PV power extraction as they exhibit low input current ripple. A 900-W prototype of a two-phase interleaved modified boost converter is designed and developed to verify the working principle of the converter and performance testing. |
