摘要： Systems and methods of controlling a dispatch operation of an energy storage system are provided. In particular, a degradation value of a present dispatch state of an energy storage system can be determined. The present dispatch state can specify one or more energy storage units presently coupled to the system. The degradation value can be determined based at least in part on one or more operating parameters, such as temperature, open circuit voltage, charge or discharge current, and/or contactor life. The degradation value can then be compared against one or more degradation values associated with one or more candidate dispatch states. A dispatch state can then be selected based on the comparison. One or more energy storage units can be selectively coupled to the energy storage system based at least in part on the selected dispatch state.

摘要： An ac-ac power converter system is provided for supplying power to an electrical load. The ac-ac power converter system provides an output voltage having variable amplitude and/or frequency. The ac-ac power converter system includes a boost inductor for applying a discontinuous current to an ac-ac power converter. The ac-ac power converter includes a rectifier circuit comprising of a first set of gate controllable active switches for converting an input ac power to a dc power and an inverter circuit comprising of a second set of gate controllable active switches for converting the dc power to an output ac power. In addition, the ac-ac power converter system includes a switch for switching between a first mode of operation and a second mode of operation. The first set of gate controllable active switches is common between the inverter circuit and the rectifier circuit and is operable at about 50 percent of duty cycle in the first mode of operation while the inverter circuit is a half bridge inverter circuit in the second mode of operation.

摘要： A method for driving a DC motor includes generating a first voltage pulse, based on a pre-determined speed input and duty cycle, and configured to generate motor current of reference current value sufficient to achieve a desired speed according to the speed input. Subsequent pulses of the voltage are generated to maintain the current substantially within a range of the reference current. Another method includes sensing and comparing motor current to reference current value and generating an error signal therebetween, which is integrated over time to generate an integrated current error, which is compared with a reference pulse. Thereafter generating applied voltage pulses configured to: switch at each instance of the integrated current error exceeding or becoming less than the reference pulse value; generate a motor current sufficient to achieve a desired speed according to a pre-determined speed input; and having substantially zero average variation from the reference current.

摘要： Systems and methods for controlling a hybrid power architecture to provide fuel or energy savings. Recharge time of an energy storage device (ESD) is reduced through the application of a controlled potential and ESD recharge time management over the life of the hybrid system through manipulation of the ESD charge state window of operation. Fuel or energy savings is achieved by controlling the partial-state-of-charge (PSOC) window of the ESD based on a recharge resistance profile of the ESD and by controlling a charging potential applied to the ESD based on a recharge current and/or the estimated recharge resistance profile of the ESD.
