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.
Connect the capacitor in parallel with the power supply terminals of the amplifier. This helps stabilize voltage fluctuations and improve performance. Similar to connecting to an amp, connect the capacitor in parallel with the power supply terminals of the amplifier. Ensure proper polarity and insulation.
Z = √ R + X Schematic of capacitive power supply circuit shown below. The working principle of the capacitive power supply is simple. From the Capacitive power supply circuit diagram we can observe the circuit is a combination of four different circuits. Voltage dropping circuit. Full-wave bridge rectifier circuit. Voltage regulator circuit.
This type of power supply uses the capacitive reactance of a capacitor to reduce the mains voltage to a lower voltage to power the electronics circuit. The circuit is a combination of a voltage dropping circuit, a full-wave bridge rectifier circuit, a voltage regulator circuit, and a power indicator circuit.
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.
The easiest thing is to discharge the cap with a resistor, set the supply output to zero volts (or turn it off) and then connect the capacitor when both are at 0 V. Then you can turn on the supply and hopefully it will come up OK with the capacitor there. Lab supplies generally seem to do fine.
