Title:
所望の負荷電力スペクトルに基づき制御される電源及び/又は安定器システム
Document Type and Number:
Japanese Patent JP2004522289
Kind Code:
A
Abstract:
A power supply and/or ballast optimizes performance of an electrical load, such as a High Intensity Discharge (HID) lamp by monitoring the current and voltage signal driving the load, and calculating a representative portion of the power spectrum being delivered to the load. The calculated portion of the delivered power spectrum is compared to a desired power spectrum, and the input signal to the load is modified in such a manner that the delivered power spectrum will more closely match the desired power spectrum. The input current and voltage, and the frequency at the load are thus not controlled directly, but are an indirect result of applying the modified input power spectrum to the load. By utilizing the input power spectrum in this manner, a power supply and/or ballast provides improved control and performance when used with electrical loads such as HID lamps.
