Improved High Step-Up Cockcroft-Walton Magnetic Coupling Inverter

An improved dual winding magnetically coupled-inductors inverter based on a Cockcroft-Walton multiplier voltage cell is proposed in this paper. Compared with the conventional generalized Z-source inverters, attains higher gain by decreasing transformer’s turns number. As result, lower cost, efficiency, larger boost factor, and density can be realized inverter. Furthermore, unlike coupled impedance source topology offers factor for small shoot-through duty ratios smoother slope, which enhances practical controllability of Hence, modulation ratio applied, results better quality inverter’s waveforms. A clamping circuit used to reduce leakage inductance effects inductors. huge spikes across bridge are eliminated. In addition, draws smooth continuous input current from dc source, suitable renewable energy sources. Detailed, theoretical analysis, simulation experimental provided.
