7.8.1 The parallel plate capacitor
... A capacitor is a device which is used to store electric charge. The simplest capacitor consists of two metal plates separated by an air gap. If the plates are connected to a battery, electrons are removed from one plate and moved around the circuit to the other plate. This leaves the first plate ...

Analysis of a New Third Harmonic Injection Active Rectifier Topology
... As can be seen from Tab.2 each three-level bridge leg mainly operates as a two-level system, the three-level operation, however, is required for smooth current control at each 60° sector transition. It is evident, that the current ratings of the NPC leg components are not ”symmetrically” (i.e., equa ...
