Research of Zero Sequence Current of Parallel System of PWM Rectifier

Taking two-level parallel system of PWM rectifier as example, the paper analyzed cause of zero sequence circulation in parallel module: the circulation is generated by difference of duty cycle of zero sequence current of two modules; generation of the circulation has no correlation with size and typ...
