Voltage Limiter Circuit Using Op-amp-Circuit Diagram Waveform
The voltage limiter circuit utilizing an operational amplifier (op-amp) serves to restrict the output voltage to predefined levels, effectively preventing it from exceeding or falling below specified thresholds. This circuit design can incorporate both positive and negative voltage limiters, which allows for comprehensive control over the output voltage range.
In the typical configuration of a voltage limiter circuit, the op-amp is employed in a feedback arrangement. The non-inverting input of the op-amp receives the input voltage signal, while the inverting input is connected to a reference voltage set by a voltage divider or Zener diode. The output of the op-amp is then fed back to the inverting input through a resistor, creating a closed-loop system.
To achieve positive voltage limiting, the reference voltage is set to the desired upper limit. When the input voltage exceeds this reference, the op-amp output will drive low, effectively clamping the output to the maximum allowable voltage. Conversely, for negative voltage limiting, a similar approach is adopted, where the reference voltage is set to the desired lower limit. This configuration ensures that the output voltage remains within the specified range, protecting downstream components from potential damage due to voltage spikes or dips.
The circuit can be visualized through a schematic diagram, which typically includes the op-amp, resistors for feedback and input scaling, and reference voltage sources. Additionally, waveforms can be illustrated to demonstrate the circuit's response to varying input voltages, showcasing how the output remains stable within the defined limits.
This voltage limiter circuit is widely applicable in various electronic systems, including power supplies, signal processing, and safety mechanisms, where voltage levels must be controlled to ensure reliable operation and protect sensitive components.Voltage Limiter Circuit Using Op-amp-Circuit Diagram, Waveform, positive and negative voltage limiters.. 🔗 External reference
