Summary form only given, as follows. In the above-named work the authors proposed a fullwave simulation method to model the air discharge mode of an electrostatic discharge (ESD) generator discharging into a product. Several small corrections should be made. First, in Fig. 3, the legend "Spice model in Fig. 2" should be changed to "Spice model in Fig. 4." Second, in Fig. 10, the...
Neutral point potential balance control is very important to three-level neutral-point-clamped (NPC) rectifiers. In this paper, the balance control strategy is studied with three-level space vector pulse width modulation (SVPWM) algorithm based on reference voltage decomposition. An improved neutral-point potential balance control strategy based on balance factor is proposed and the principle is analyzed...
Through the analysis of the problems existed in the passive harmonic filters, this paper proposed a real time intelligent tuning technology and its application in passive harmonic filters. The control algorithm, parameter setting and protection coordination are presented in an application case.
