摘要： A system for transmitting electric power from an electric power transmission apparatus (10) to an electric power reception apparatus (50) by using electromagnetic induction between a power receiving coil (60) and a power transmitting coil (40). The electric power transmission apparatus (10) comprises an electric power switching circuit (14), a first capacitor (20) and an electric power derivation circuit (30). The electric power switching circuit (14) includes a switching element (16) and an output point (P) and switches the switching element (16) at a predetermined switching frequency (f), thereby causing the electrical potential at the output point (P) to exhibit a predetermined variation, wherein the predetermined variation is an electrical potential variation obtainable by the half-wave rectification of a sinusoidal wave variation which has a predetermined amplitude. The first capacitor (20) is coupled between the output point (P) and a first constant electrical potential (ground). The electric power derivation circuit (30) includes the power transmission coil (40) and is formed to cause an AC variation of the foregoing predetermined variation to occur between the both ends of the power transmission coil (40). The electric power derivation circuit (30) is coupled between the output point (P) and a second constant electrical potential (ground).

摘要： An inverter system for driving electrical loads such as multi-phase induction motors is disclosed utilizing five single-phase inverter cells configured in a wye configuration. Inverter cells such as neutral-point-clamp inverter cells are configured to generate a voltage waveform between two output terminals and further configured with a terminal providing a neutral voltage reference point with respect to each of the two output terminals. The inverter cells may be configured with the neutral voltage reference points connected together and with one output terminal from each inverter cells connected together to provide three outputs of the inverter system at different voltage phases and with the common neutral reference point as the wye connection of the three outputs. The other three single phase inverter cells may be added to each of the three outputs to boost the output voltage of the inverter system and decrease the maximum voltage requirements on each inverter cell.
