LLCLC Resonant Converter Based Pseudo DC Link Inverter

Technological advancements in solar power systems necessitate highly reliable inverters with a high efficiency and small size. An LLC resonant converter-based pseudo Direct Current (DC) link offer these qualities to some extent. The circuits of conventional DC lack the ability attain zero gain cannot handle variable frequency control which turn requires very large filters produce pure sinusoidal output voltages for grid. usage consequences enhanced price size inverters; moreover, reliability is also reduced. We propose novel topology inverter based on an LLCLC converter. proposed does not require filters, because it generates rectified voltages. additional parallel LC component added series circuit, makes able through infinite circuit impedance. 400 W 40 V input designed simulated OrCAD PSpice software. results showed that there significant improvement achieving gain. possible lowest achieved approximately 0.125. technique attested be more efficient than those formerly used, subsequently contributing satisfying outcomes.
