| 摘要 |
A combined system incorporating one or more DC/AC inverter systems or sub-systems, and one or more constant current sources and/or constant current sinks is disclosed. Various embodiments of this invention simultaneously deliver AC electrical power, as well as source or sink constant current to or from one or more electrical loads. Powered by one or more DC power sources, this invention combines into a single standalone multi-function unit the capability to deliver AC electrical power and also constant source or sink currents for LED lighting for general illumination or signaling, and optionally, also for charging or discharging one or more batteries. Examples of constant current loads driven by this invention include, but are not limited to, visible, infrared or ultra-violet LEDs, laser diodes and batteries of arbitrary composition, construction and voltage/current ratings in controlled charge or discharge mode. |
