6 FAQs about [Power supply negative output terminal capacitor]

Why are capacitors placed across power supply terminals?

Based upon our discussion it should now be understood that capacitors are often placed across the power supply terminals at the load to reduce the voltage excursions caused by load current transients and the finite bandwidth response of the power supply.

What is the purpose of capacitors on the output of a power supply?

Where are the capacitors located on a power supply?

When we look at almost any power supply application circuit there will be capacitors on the output of the power supply located at the load. One question often asked of power supply vendors is “Why are the output capacitors required on a power supply and how are the capacitors selected?”.

What happens if a negative supply voltage is changed abruptly?

If the negative supply voltage is changed abruptly, the integrator ampli-fier will force the output to follow the change. When the entire amplifier is in a closed-loop configuration the resulting error signal at its input will tend to restore the output, but the recovery will be limited by the slew rate of the amplifier.

Can a capacitive power supply fail?

In a capacitive power supply the load and series resistor could theoretically keep the short-circuit current low enough for the fuse not to trip and still cause damage to the load or other parts eventually. This failure can also be avoided by the use of a low voltage varistor (or MOV) after the series capacitor.

Can a capacitive power supply have a low power factor?

The low power factor is not an issue because the capacitive power supply power rating is not high enough for a power factor correction (PFC) to be required. The Standard IEC 61000-3-2 requires PFC for power supplies only with a power output of more than 25 W. 04. CONSTRUCTION OF A CAPACITIVE POWER SUPPLY
