Integrated circuits such as the LM 317 and 723 enable us to fine-tune the output voltage to a precise constant value. The figure below shows the LM317 voltage regulator.The output voltage can be adjusted by adjusting the values of resistances R 1 and R 2 ually, coupling capacitors of values about 0.01µF to 10µF need to be connected at the output and
In the power supply block diagram, the input voltage is 230 Volts however in practice; there are significant differences within the AC supply mains voltage. As this mains supply voltage is i/p to the normal power supply, the bridge rectifier''s filtered o/p is approximately directly proportional toward the AC mains voltage.

In the world of electronics, power supply circuits play a crucial role in providing the necessary power to operate various electronic devices. One popular type of power supply circuit is the switch mode power supply (SMPS). It is widely used in applications where efficiency, size, and weight are the key factors.
Circuit diagram of a capacitive power supply: The vector diagram makes it clear: The majority of the input voltage drops out at the reactance of the capacitor with virtually no power dissipation being created in the capacitor. As the capacitor is directly connected to the power supply, very high demands are made on its reliability.
The capacitive power supply circuit is a mostly capacitive load as seen from the input. As we expected, there are no EMC compliance issues to consider in our example circuit. 06. SUMMARY
INTRODUCTION A capacitive power supply is a very low-cost AC/DC converter without a transformer or switching components. With a very small parts count, these circuits can provide a DC voltage for low-power applications. In addition, because no high-speed switching is occurring, no EMI noise is generated.
In contrast to conventional designs, the capacitive power supplies are short-circuit-proof at the output. Circuit diagram of a capacitive power supply: The vector diagram makes it clear: The majority of the input voltage drops out at the reactance of the capacitor with virtually no power dissipation being created in the capacitor.
The power rating and the capacitance are two important aspects to be considered while selecting the smoothing capacitor. The power rating must be greater than the off load output voltage of the power supply.
I = 230 V / 14. 4 = 15.9 mA. Therefore if a 0.22 uF capacitor rated for 230 V is used, it can deliver around 15 mA current to the circuit. But this is not sufficient for many circuits. Therefore it is recommended to use a 470 nF capacitor rated for 400 V for such circuits to give required current.
