Abstract:
A DC power system (1) capable of serving all electrical end-use applications such as maintains normal lighting conditions by lighting fixtures (Lights) requiring DC electrical power as well as other DC compatible loads. A power control (Control Means) and conversion device (DC Rectifier Means) receives AC electrical power from a public utility (AC line) or similar AC source and converts (DC Rectifier) AC power to DC power and delivers low voltage DC electrical power to lighting fixtures (Lights) or any DC compatible end-use. An alternative DC power source (Batt) or sources may be connected to the device (1) and within the device (1) combined with the converted source in service to the load (Lights). A standby rechargeable battery (Batt) serves as an alternative DC source and may be provided to maintain power during line power outages. Optionally, an alternative DC power source such as a photovoltaic DC electrical power source (PV) may be connected to the power control device (1), to provide DC electrical power proportionally to the DC loads. In a further embodiment, a variety of power sources may be connected to the power device such as a gas driven cogenerator unit to supply DC electrical power. This device may also serve in a stand alone application without AC line grid supplies.

Abstract:
A power transfer system includes a series of energy storage modules (ESMs) or energy storage devices (ESDs) that are coupled together to be able to transfer power between one another, as well as receive power from a power source, such as an onshore power generator. The energy storage modules may be hybrid energy storage modules, each including an electrical-machine-inertial energy store and an electro-chemical energy store. The energy storage modules are configured to receive constant-current DC or AC input from the power source, and are able to provide constant-current and constant-voltage output, either sequentially or simultaneously. The power transfer system allows the modules to operate independently or in conjunction with one another, should some of the connections of the system be broken. The energy storage modules may be used to provide power to underwater systems, for example sonar systems, weapons systems, or underwater vehicles.
