A simple DC-Link Voltage Balancing Strategy for NPC Three-level Inverters

2023 25th European Conference on Power Electronics and Applications (EPE'23 ECCE Europe), 2023
Three-level neutral point clamped PWM inverters overcome some limitations of two-level inverters in medium voltage applications, leading to lower device ratings and greater efficiency. However, they are burdened by an intrinsic drawback of the neutral point clamped structure, which causes, under some operating conditions, a voltage imbalance of the DC ...
