Improved Cockcroft-Walton Single Stage High Voltage Gain Inverter

This paper presents an improved Cockcroft- Walton Single stage high voltage gain inverter. The impedance network consists of a coupling inductor and an improved Cockcroft-Walton booster converter. A high quality output waveform is obtained with a smaller duty cycle and a larger modulation index. The proposed inverter reduces the ratio of turns of the coupling inductance, so it is lighter in weight and smaller in size. The 700W prototype designed by the laboratory tests the performance of the proposed circuit. Theoretical analysis, simulation and experimental results are completely consistent. The validity and practicability of the proposed converter are verified.
