25B-D2P3N114 Allen- Bradley 可通過調(diào)節(jié)電源的頻率和電壓來驅(qū)動電機
25B-D2P3N114是一款變頻驅(qū)動器它是一種電機控制設備，可通過調(diào)節(jié)電源的頻率和電壓來驅(qū)動電機。除了對電機的啟動和停止過程中的加速和減速進行控制外，它還被稱作可調(diào)速驅(qū)動器、可調(diào)頻驅(qū)動器、變速驅(qū)動器、頻率轉(zhuǎn)換器、電源轉(zhuǎn)換器等。
25B-D2P3N114的歷史可以追溯到1960年代，當時電力電子器件如晶閘管及其升級產(chǎn)品開始普及，但其調(diào)速性能無法滿足需要。到了1970年代，脈寬調(diào)制變壓變頻（PWM－VVVF）調(diào)速的研究取得了突破。隨著1980年代微處理器技術(shù)的完善，各種優(yōu)化算法得以實現(xiàn)。到了1980年代中后期，VVVF變頻器技術(shù)在美、日、德、英等發(fā)達國家得到了實用化，并投入市場廣泛應用。
25B-D2P3N114的類型繁多，已衍生出了許多適用于各類應用的單相和三相變頻器。它們的區(qū)別主要在于頻率和電壓控制方式的不同，以及諧波抑制技術(shù)的不同。變頻器中常用的三大變頻設計包括：脈沖寬度調(diào)制（PWM）、電流源逆變器和電壓源逆變器。其中，PWM技術(shù)最為常見，它通過多次開啟和關(guān)閉變頻器的功率逆變器設備（如晶體管或絕緣柵雙極型晶體管），使電壓的均方值達到合適水平，從而改變輸出頻率和輸出電壓。

The 25B-D2P3N114 is a variable frequency driver. It is a motor control device that drives a motor by adjusting the frequency and voltage of the power supply. In addition to the control of acceleration and deceleration during the start and stop of the motor, it is also called adjustable speed driver, adjustable frequency driver, variable speed driver, frequency converter, power converter, etc.
The history of the 25B-D2P3N114 dates back to the 1960s, when power electronics such as thyristors and their upgrades became popular, but their speed regulation performance was not enough to meet the needs. In the 1970s, the research of pulse width modulation variable voltage frequency conversion (PWM-VVVF) speed regulation made a breakthrough. With the improvement of microprocessor technology in the 1980s, various optimization algorithms were realized. By the late 1980s, VVVF inverter technology in the United States, Japan, Germany, Britain and other developed countries have been practical, and put into the market widely used.
The variety of 25B-D2P3N114 has resulted in a number of single – and three-phase converters for a wide range of applications. The difference between them mainly lies in the difference in frequency and voltage control methods, and the difference in harmonic suppression technology. Three commonly used frequency conversion designs include: pulse width modulation (PWM), current source inverter and voltage source inverter. Among them, PWM technology is the most common, it turns on and off the power inverter device (such as transistor or insulated gate bipolar transistor) of the inverter several times, so that the mean square value of the voltage reaches the appropriate level, so as to change the output frequency and output voltage.
