摘要： A pressurized fluid system provides electrical power to a load and includes a fluid motor, a generator, an energy storage device and a controller. The system supplies fluid to the fluid motor, which provides a generator with power producing a voltage used to supply power to a load and provide energy to the energy storage device. The controller selects which of various sources within the system provides fluid to the fluid motor based on the operating mode of the system. When fluid supplied to the fluid motor is discontinued, the energy storage device discharges providing power to the load.

摘要： A high frequency, full bridge, resonant DC to DC converter provides a main DC output voltage that is regulated by adjusting the phase shift of the input power to a main input transformer and at least one additional DC output voltage that is regulated on the secondary side of the power input transformer. A main DC output voltage is regulated by a full bridge resonant switching converter with lossless switching of input power devices. At least one additional secondary winding on the transformer supplies a second DC output voltage that is regulated independently of the main DC output voltage. Two switching devices are used for each auxiliary DC output to regulate each auxiliary output voltage by adjusting the length of the on time of the pulses from the transformer's auxiliary secondary windings. Soft switching techniques are used to ensure that the switching devices turn on when the voltage across them is effectively zero.

摘要： A transformerless photovoltaic system that may benefit from inverter topologies more suitable for ripple current cancellation techniques is provided. In one exemplary embodiment, the system may combine basic modules of straightforward inverter topologies to meet requirements for higher power applications and may comprise a bipolar photovoltaic array, and a full-bridge inverter electrically coupled to the bipolar photovoltaic array. The full bridge inverter may comprise first and second inverter legs that may be arranged to energize two phases of a grid electrically coupled to the photovoltaic system. In one exemplary embodiment, switching signals applied to switching devices in each of the first and second inverter legs may be adjusted relative to one other to reduce ripple current therein, thereby reducing the size of components used by the system.
