Cockcroft Voltage Multiplier Converter Based Three-Phase Inverter for High Power Applications
AbstractThe dc-dc converter converts the low dc input voltage to high voltage without using a step-up transformer. The typical dc-dc converter generates high voltage using a high duty cycle, but the suggested converter generates high voltage using a low duty cycle. The Cockcroft voltage multiplier uses the diode and capacitor to increase the potential at the output of the converter and gain high DC voltage. The proposed converter is connected to the three-phase inverter and feed into the ac application. The capacitor is utilized to boost the voltage and operate as a transformer since the switch in the converter is turned off. The capacitor discharges the power, adding to the supply side voltage. The pulse width modulation is used to control and regulate the voltage and current of the inverter. The voltage and current of three-phase inverter simulation are verified using the Matlab / Simulink software.
