Abstract
A device for increasing the fundamental power yield of a self-commutated inverter with a capacitive storage device. The device is connected to the outputs of a self-commutated inverter, providing at least one single-phase cascade per R, S and T phase. Each single-phase cascade includes a capacitive storage device and a switching device with which the capacitive storage device can be switched into phase and out of phase with respect to the phase with which the cascade is associated.
Claims18
A device for increasing the fundamental power yield of a self commutated inverter having a plurality of capacitive storage devices in a multiplex network said device comprising:
- a single phase cascade for each phase of the multi-phase configuration wherein each single phase cascade includes,
- i. a capacitive storage device;
- ii. a switching device for selectively switching the capacitive storage device into phase and out of phase with respect to the phase with which that cascade is associated.
