Final answer:
The base voltage drives the transistor switches in the inverter stage, acting as a valve that controls the current flow from the emitter to the collector in a junction transistor.
Step-by-step explanation:
The transistor switches in the inverter stage are driven by the base voltage. In a junction transistor, which consists of three parts—emitter, base, and collector—the voltage that is applied to the base acts as a valve that controls the flow of electric current from the emitter to the collector. When a small positive base voltage is applied, it allows a larger collector current to flow through the device. This mechanism is vital for the operation of inverters in electronic circuits, as it enables the transistor to switch states between on and off, which is essential for converting direct current (DC) to alternating current (AC).
For example, in amplification applications like a loudspeaker system, the sound waves from a microphone can cause a diaphragm to move, generating a tiny positive voltage at the base of the transistor. This base voltage is key to controlling the large collector current required to drive the loudspeaker.
The transistor switches in the inverter stage are driven by the base voltage.
A junction transistor has three parts: emitter, base, and collector. Voltage applied to the base acts as a valve to control electric current from the emitter to the collector.
The base voltage controls the current flow through the transistor and determines its on/off state.
