| Abstract |
A class of polyphase power converters is presented which operate with a high frequency resonant link between the input and output switching matrices. The incoming low frequency power is transformed to a substantially higher frequency directly . The high frequency link includes series-resonant circuits which facilitate the natural current commutation of electronic switching elements like thyristors. The energy is transformed from the high-frequency link to a lower frequency output circuit via another switching matrix. A new method of switching (soft-switching) is introduced to eliminate the dynamic losses. The innovative aspects are in the techniques used to control the flow of energy into and out of the resonant LC circuit. The new multi -purpose power converter can transform electric energy from a polyphase AC source to an AC load of another voltage, frequency or waveform, including DC. The direction of the flow of power is reversible. |
