INSTRUMENT POWER CONTROLLER, AND ELECTRIC POWER CONTROL METHOD FOR ADAPTABLE PROVIDING AN OUTPUT VOLTAGE AND OUTPUT CURRENT TOGETHER MAINTAIN A CONSTANT OUTPUT ELECTRIC POWER

摘要

instrument power controller, e.g. electrical control method for adaptively providing an output voltage and an output current which together maintain a substantially constant output electrical energy. instrument power controller (120) for adaptively providing an output voltage v0 and an output current i, which together kill a substantially constant output electrical power p is provided. controller (120) includes inputs (121) for receiving input power p ~ i, outputs (122) for providing substantially constant output energy p ~ for a variable impedance load 1, and a communication path (126). ) to receive a charge voltage v i. the instrument power controller 120 is configured to determine an input voltage v i and an input current i i to determine an effective resistance r i. of a load 1 and set the output voltage v and the output current i based on the input voltage v i, the input current i i, and the effective resistance r i. the output voltage v i is substantially independent of the input voltage v i. the output voltage v0 and the output current v0 and the output current i3 are varied to maximize a charge energy p i while maintaining the substantially constant output electrical energy p i.
