在负载瞬变条件下提供可变电压波形的AC电源设备和方法

本发明主题的某些实施方式提供用于操作不间断电源（UPS）的方法，该UPS被配置为从第电源和第二电源（如，市电电源和电池，或其它备用电源）向负载供电。所述方法配合负载在第电源和第二电源之间的转变而操作UPS来短暂地提供修改过的电压波形。例如，修改过的电压波形可以提供短暂地增加的电压变化率，以补偿负载的瞬间电流需求。 Some embodiments of the inventive subject matter provide methods of operating an uninterruptible power supply (UPS) configured to provide powe...

Summary:本发明主题的某些实施方式提供用于操作不间断电源（UPS）的方法，该UPS被配置为从第电源和第二电源（如，市电电源和电池，或其它备用电源）向负载供电。所述方法配合负载在第电源和第二电源之间的转变而操作UPS来短暂地提供修改过的电压波形。例如，修改过的电压波形可以提供短暂地增加的电压变化率，以补偿负载的瞬间电流需求。 Some embodiments of the inventive subject matter provide methods of operating an uninterruptible power supply (UPS) configured to provide power to a load from first and second power sources, e.g., from a utility source and a battery or other backup source. The methods include operating the UPS to momentarily provide an altered voltage waveform in coordination with a transition of the load between first and second power sources. For example, the altered voltage waveform may provide a momentarily increased voltage rate of change to compensate for a transient current demand presented by the load.
