High efficient and high gain boost converter with soft switching capability connected to grid using dq axis current control

Renewable sources like solar PV arrays are generally operated at low voltages due to safety issues. For applications such as grid connected systems, it requires boosting high voltage which leads reduction in efficiency. To solve this, a new gain and efficient boost converter is combination of buffer capacitor, passive clamp recovery circuit restore leakage energy coupled inductor presented. The magnetic field the linked stores obtained from supply. A network recovers that stored inductance, enhances improves overall system High duty ratios not essential achieve higher gain, hence reverse problem diode prevented. Moreover, decreases stress switch, thus minimum rating switch be used, result, system's total efficiency improves. This output fed input single phase full bridge inverter also synchronized by using d-q axis current controller. performance powers injected analyzed connecting resistive load.
