6 FAQs about [Sarajevo phase-shift capacitor test]
Does a series capacitor always contribute to a 0° phase shift?
In this case, the phase shift starts at +90°, and the filter is a high-pass. Beyond the cutoff frequency, we eventually settle to 0°. So we see a series capacitor will always contribute between +90° and 0° phase shift. With this information at our disposal, we can apply an RC model to any circuit we wish.
Can a shunt capacitor cause a phase shift?
A shunt capacitor will cause between 0° and -90° phase shift on a resistive load. It’s important to be aware of the attenuation too, of course. A similar look at a series capacitor (for example, an AC-coupling cap) shows the typical effect for that configuration. Figure 3. Series capacitor circuit... Figure 4. And its bode plot
What is a cutoff frequency for a capacitor?
From our experience, we would expect there to be a cutoff frequency of 53 Hz, below which there should be a 180° phase shift (no effect from capacitor) and above which there would be 180° - 90° = 90° phase shift (as well as a lot of loss). Simulation confirms our suspicions: Figure 8.
What is phase shift & how does it affect a circuit?
This article talks about phase shift, the effect of a circuit to cause a lead or lag of voltage or current from its input to its output. In particular, we’re going to concern ourselves with how reactive loads and networks will affect the phase shift of a circuit.
Does a shunt capacitor affect the output phase of an RC circuit?
We know from basic circuit analysis that the voltage phase shift in an RC circuit will vary from 0° to -90°, and simulation confirms this. Figure 2. Bode plot of the output of our shunt capacitor circuit. For low frequencies, the output phase is unaffected by the capacitor.
How can a module of impedance be calculated with phase shift?
From voltage and current amplitude values, module of impedance can be calculated, and with phase shift it is possible to split real and imaginary part of the impedance. In this case, the real part of impedance is of interest, because it represents AC internal resistance of battery.
