On the basis of the original current loop, a PI control is used to minimize the intrinsic DC components. The Kalman filter is creatively introduced to narrow the random components caused by measurement errors. Mathematical analysis proves the feasibility of the DC component suppression scheme applied to the NPC inverter.
Modulation techniques or auxiliary circuit schemes might be employed to decrease the CMV 19, 20. Dead time in power electronic inverters causes significant spikes in common mode voltage (CMV) due to all switches being off, resulting in unplanned zero voltage vectors. Mathematically, these spikes can reach up to ±udc/2.
For this purpose, pulse 1 and pulse 2 and pulse 3 are initially determined using a comparator. Then, using the relationships (13)–(15), each three phases voltage are generated, which results in production of zero CMV in ideal mode. There are four switches on each leg of a five-level inverter.
Fig. 15b illustrates the performance of proposed inverter by measuring the voltage of phase A to nodes n and 0. These voltages are approximately equal which eventuate the nodes n and 0 catch same potential. Therefore, the CMV must be zero. The output currents of phase A and phase B have been exposed in Fig. 15c.
