摘要： An uninterruptible power supply system has a flywheel system/battery combination as a source of back-up DC power. When power is restored after a power outage, a controller of the uninterruptible power supply system controls the rectifier to keep its DC output voltage sufficiently low so that only the flywheel system of the flywheel system/battery combination is initially recharged. Once the flywheel system is recharged, the controller is configured to raise the voltage of the rectifier's DC output voltage to the nominal DC output voltage of the rectifier, both for recharging the battery pack of the flywheel system/battery combination and to provide DC power to an inverter of the uninterruptible power supply system.

摘要： A power control system for providing power sharing is provided. An energy storage device is configured to supply a first portion of power of an electrical power as a total load power and an engine-driven electrical machine is configured to supply a second portion of power of the total load power. A power converter is electrically coupled to the energy storage device and the engine-driven electrical machine such that the power converter is configured to supply the total load power to an electrical load device. A controller is coupled to the power converter and the controller receives characteristic data from at least one of the energy storage device, the engine-driven electrical machine, and the electrical load device. Based on the received characteristic data, the controller determines a power sharing proportion of a power sharing amount of each of the first portion of power and the second portion of power of the total load power to be supplied via the power converter to the electrical load device.

摘要： The invention in the simplest form is an improved hybrid power converter with uninterruptible power supply (UPS) and power quality capabilities as well as an integrated variable speed power source and control method that is used to generate high quality, uninterruptible AC power utilizing fewer batteries and operating at optimum fuel efficiency and with reduced emissions. The variable speed generator control scheme allows for load adaptive speed control of a power source such as an engine (20) and generator (10). The transformerless hybrid power converter topology and control method provides the necessary output frequency, voltage and/or current waveform regulation, harmonic distortion rejection, and provides for single-phase or unbalanced loading. The transformerless hybrid power converter also provides inline or offline UPS capability, line voltage and/or frequency sag and surge compensation, peak shaving capability, VAR compensation and active harmonic filtering.
