A unified constant-frequency integration (UCI) controller for a three-phase star-connected switch three-level rectifier (VIENNA) with unity-power-factor-correction is proposed. One of advantages of this rectifier is that the switch voltage stress is one half of the total output voltage. The propo...

The geometric sum of the complex effective values of the Z “1 = 30 e j25°Ω ; Z “2 = 28 e j30°Ω ; Z “3 = 32 e j35°Ω phase currents (see Figure 2) is zero and thus: (Star connection; asymmetry 7 %); U1N + UNN U 2N + UNN U3N + UNN What is the value ...
Due to this fact, the installation of the inner wiring is substantially more complex and time-consuming in comparison with the delta connection. [0005] The object of the present invention is thus to provide a three-phase electrical can capacitor having plastic-film capacitor windings arranged in ...
