Разработан и изготовлен многопереходный преобразователь мощности лазерного излучения на основе арсенида галлия. Единичный чип преобразователя способен выдать 1,7 Вт электрической мощности при освещении излучением с длиной волны 880 нм и мощностью 4,78 Вт. Такие чипы, пакетированные в корпус транзисторного типа, способны выдавать мощность 1 Вт при мощности освещения 2,246 Вт, демонстрируя эффективность преобразования 44,5%. Для целей практического применения реализован соединенный с корпусом преобразователя контроллер мощности на основе техники отслеживания точки максимальной мощности (ОТММ, англ. maximum power point tracking, MPPT). Измерения показали, что на выходе контроллера можно достичь 88,1% от выхода пакетированного преобразователя мощности.
Ключевые слова: преобразователь мощности лазерного излучения, арсенид галлия GaAs, контроллер мощности, отслеживание точки максимальной мощности.
A multi-junction GaAs laser power converter is designed and fabricated. One bare laser power converter chip can output an electric power of 1.7 W under a light illumination at 808 nm with an optical power of about 4.78 W. Then, the laser power converter is packaged in the transistor outline type. The transistor outline type packaged laser power converter can output an electric power of 1 W for an input light power of about 2.246 W, which results in a conversion efficiency of 44.5%. For practical applications, a power manager module based on the maximum power point tracking technique is also realized and connected to the packaged laser power converter. In the measurement, at the output of the power manager module, more than 88.1% of laser power converter’s output electric power can be extracted.
Keywords: laser power converter, GaAs, power manager, maximum power point tracking, transistor outline type.
