15.2 Simple AC Circuits
The vertical axis on a phasor diagram could be either the voltage or the current, depending on the phasor that is being examined. In addition, several quantities can be depicted on the same phasor diagram. For example, both the current i R (t) i R (t) and the voltage v R (t) v R (t) are shown in the diagram of Figure 15.6(b).(b).
Improved Z-Source Inverter With Reduced Z-Source Capacitor Voltage Stress and …
This paper proposes an improved Z-source inverter topology. Compared to the traditional Z-source inverter, it can reduce the Z-source capacitor voltage stress significantly to perform the same voltage boost, and has inherent limitation to inrush current at startup. The control strategy of the proposed Z-source inverter is exactly the same as …

DC-Link Capacitor Current Stress Minimization Strategy for Paralleled Three-Phase Voltage-Source …
Interleaving technology in paralleled three-phase voltage-source converters (VSCs) can reduce the dc-link ripple current to improve the power density and lifetime of the dc-link capacitors. However, the carrier-based phase-shifting method commonly used for interleaving cannot achieve the minimum dc-link capacitor current …

OverviewHistoryTheory of operationNon-ideal behaviorCapacitor typesCapacitor markingsApplicationsHazards and safety
In electrical engineering, a capacitor is a device that stores electrical energy by accumulating electric charges on two closely spaced surfaces that are insulated from each other. The capacitor was originally known as the condenser, a term still encountered in a few compound names, such as the condenser microphone. It is a passive electronic component with two terminals.
