摘要： Embedding electrical machines in gas turbine engines has particular advantages by avoiding the need to provide mechanical connections. However, electrical machines such as switched reluctance electrical machines require relatively large electrical capacitors to accommodate and filter voltage variations in the phases of the electrical machine. Generally, the electrical machine will have a motoring period or generating period with a spacer period between. By injecting electrical current as electrical power in the spacer period, there is limited effect upon net torque within the electrical machine or electrical power generation. However, such stored electrical power in an inductive winding element of the electrical machine augments power pulses provided by a power source incorporating an electrical capacitor. In such circumstances, a smaller sized electrical capacitor can be used.

摘要： Electrical machine arrangements have advantages with regard to providing local electrical power and starting. Embedding such electrical machine arrangements in machinery such as gas turbine engines is advantageous in removing mechanical linkages and reducing aerodynamic drag. However, the components utilized must be able to withstand harsh environmental conditions and therefore the DC link capacitor used for smoothing of voltage fluctuations are limited to relatively low capacitance densities. Low density DC link capacitors require large sizes which render electrical machines less acceptable for embedded usage. By providing offset of electrical current in inductance elements such as stator windings and stator coils of electrical machines in dead periods of the cycle a reduction in DC link capacitor requirements is achieved reducing the size, weight and complexity of installing electrical machines in gas turbine engines.
