6 FAQs about [Household power supply capacitor]

What type of capacitor should a power supply use?

The value and type of capacitor used will depend upon the bandwidth of the power supply, the magnitude of the load transient, the frequency components of the load transient, and the acceptable level of voltage excursion caused by the load transients.

What are the components of a capacitive power supply?

Full-wave bridge rectifier circuit. Voltage regulator circuit. Power indicator circuit. A capacitive power supply has a voltage dropping capacitor (C1), this is the main component in the circuit. It is used to drop the mains voltage to lower voltage. The dropping capacitor is non-polarized so, it can be connected to any side in the circuit.

How to choose a voltage dropping capacitor for capacitive power supply?

Selection of the voltage dropping capacitor for capacitive power supply, some technical knowledge, and practical experience requires to get the desired voltage and current output. An ordinary capacitor will not do the same job since the mains spikes will make holes in the dielectric, and the capacitor will fail to work.
