    摘要: A downhole power system includes an energy storage adapted to operate at high temperatures, and a modular signal interface device that serves to control the energy storage component as well as offer a means of data logging at high temperatures. The controller is fabricated from pre-assembled components that may be selected for various combinations to provide desired functionality. The energy storage may include at least one ultracapacitor.
