SVM Strategies for Simultaneous Common-Mode Voltage Reduction and DC Current Balancing in Parallel Current Source Converters

Parallel-connected current source converters (CSCs) can be used to increase the power capacity and the flexibility of power conversion systems. However, this type of configuration needs to obtain proper dc current balancing through either passive methods or active PWM (pulse width modulation) strategies, in order to avoid overloading problems of a single converter. For the operation of transformer...
