摘要： An energy storage system stores potential energy and providing a regulated output of electrical energy for powering an electrical load. The system includes an array of storage capacitors including a plurality of storage capacitors coupled in series. A balance control device balances the voltage on each of the storage capacitors in the array. An input control device manages the input for charging the storage capacitor array. An output power supply has an input coupled to the storage capacitor array and provides regulated power to an electrical load. A power monitor device electrically decouples the storage capacitor array from the electrical load when the total voltage of the storage capacitor array falls below a preset minimum level.

摘要： An electrical system includes a cycloidal electric machine having a stator and an eccentric rotor. An airgap is defined between the stator and the rotor. The rotor moves with two degrees of freedom (2DOF), including rotating motion about the rotor axis and orbiting motion about the stator axis. A rotor constraint mechanism (RCM) constrains rotor motion to enable output torque to transfer to a coupled load in at least one of the 2DOF. The machine includes a structural element connected to or formed integrally with the rotor or stator that minimizes and substantially equalizes a size of the airgap around a circumference of the rotor. The element may be a crescent-shaped race of ferrous material coupled to a rotor shaft. The stator may include stator teeth, the rotor may include lobes, and the stator teeth and rotor lobes may have cycloid-profiled surfaces that form the structural element.

摘要： Power supply for an inverter and method for operating power supply. Power supply includes a throttle arranged to connect an output end of the inverter to an electric power supply network; a secondary-side auxiliary winding that is arranged on the throttle to transmit an output voltage (UA) of the inverter to a secondary side of the throttle; and a comparator unit. The comparator unit compares a voltage (U1) of the electric supply network with the voltage (U2) of the secondary side of the throttle, to supply, depending upon a result of the comparison of the electric supply network voltage (U1) to the secondary side voltage (U2) of the throttle, electric power to the power supply either from the electric supply network or via the secondary-side auxiliary winding.

摘要： We describe a photovoltaic (PV) panel system comprising a PV panel with multiple sub-strings of connected solar cells in combination with a power conditioning unit (microinverter). The power conditioning unit comprises a set of input power converters, one connected to each sub-string, and a common output power conversion stage, to provide power to an ac mains power supply output. Integration of the micro-inverter into the solar PV module in this way provides many advantages, including greater efficiency and reliability. Additionally, embodiments of the invention avoid the need for bypass diodes, a component with a high failure rate in PV panels, providing lower power loss and higher reliability.

摘要： A static synchronous compensator that generates a second axis voltage command from the difference between the DC voltage converted by a single-phase voltage AC-DC conversion circuit and a set DC voltage command. When the voltage (the voltage of an AC terminal) of the single-phase AC power system increases, since the difference between the voltage of the AC terminal and an internal electromotive force increases, the static synchronous compensator carries out a PWM control to decreases the voltage of the AC terminal side of the single-phase voltage AC-DC conversion circuit. Since the voltage of the single-phase voltage AC-DC conversion circuit becomes lower than the voltage of the single-phase AC power system, an ineffective current flows from single-phase AC power system in the static synchronous compensator so that the voltage of the single-phase AC power system can be decreased.
