A novel fast open-transistor diagnosis approach for voltage-source inverters (VSI) based on calculated bridge arm pole-to-pole (PTP) voltages is proposed in this paper. The theoretical PTP voltages can be calculated with duty cycle ratio and DC input, and the real PTP voltages can be calculated with output voltages and currents. When no fault occurs, there should be no difference between the theoretical...
Three-phase inverter has been widely applied in various applications, and lots of control schemes are investigated for the inverter powering nonlinear load, aiming to achieve favorable performance. However, the model currently proposed for inverter is based on linear load, which is not suitable for condition with nonlinear load. In this paper, a novel modeling method for three-phase inverter powering...
In this paper, diffuse discharges sustained by nanosecond pulses are obtained in air gaps with a multi-needle-to-plane discharge electrode configuration at atmospheric pressure. A repetitive nanosecond generator with a rise time of 70ns and a full width at half maximum of 100ns is employed to drive diffuse discharges. Characteristics of the diffuse discharge were investigated by analyzing voltage-current...
The work attempts to investigate the thermal-mechanical behaviors of an advanced flexible electronics technology during the bonding process and under four-point bending (FPB) and static bending (SB). The flexible technology implements an epoxy-based anisotropic conductive film (ACF) to form fine-pitch and reliable interconnects of Integrated circuits (IC) bumps on flex substrates. The paper starts...
