ABB KX8974c V24 HIEE320606R1有源元件是一种具有模拟电子滤波器的器件，能够放大信号或产生功率增益。有源元件有两种:电子管和半导体或固态器件。典型的有源元件是振荡器、晶体管或集成电路。

有源元件作为设备中的交流电路，用于增加有功功率、电压或电流。有源元件能够做到这一点，因为它由与电信号分开的电源供电。

ABB KX8974c V24 HIEE320606R1大多数电子器件都是半导体，其中最常见的是晶体管。放大器中通常使用基本晶体管，它使用直流(DC)电源提供必要的功率来增加有效电流I/O信号。

有源器件具有控制电子流的能力，并且允许电压控制电流或者允许另一个电流控制。压控器件，如真空管，控制自己的信号，而电流控制器件，如双极结型晶体管，允许一种电流控制另一种电流。

ABB KX8974c V24 HIEE320606R1所有的有源元件都需要一个能量源，这个能量源通常来自DC电路。此外，有源器件通常可以将功率注入电路，例如晶体管、三极管真空管或隧道二极管。

非有源元件称为无源元件。它消耗能量，不具备提升动力的能力。基本的无源元件包括电容、电阻和电感。

The ABB KX8974c V24 HIEE320606R1 active element is a device with an analog electronic filter capable of amplifying a signal or generating power gain. There are two types of active components: tubes and semiconductor or solid-state devices. Typical active components are oscillators, transistors, or integrated circuits.

Active components act as AC circuits in a device to increase active power, voltage, or current. The active component is able to do this because it is powered by a power source separate from the electrical signal.

ABB KX8974c V24 HIEE320606R1 Most electronic devices are semiconductors, the most common of which are transistors. A basic transistor is typically used in an amplifier, which uses a direct current (DC) power supply to provide the necessary power to increase the effective current I/O signal.

Active devices have the ability to control the flow of electrons and allow a voltage to control the current or allow another current to control it. Voltage-controlled devices, such as vacuum tubes, control their own signals, while current-controlled devices, such as bipolar junction transistors, allow one current to control another.

ABB KX8974c V24 HIEE320606R1 All active components require an energy source, which usually comes from a DC circuit. In addition, active devices can often inject power into a circuit, such as transistors, triode vacuum tubes, or tunnel diodes.
