How do you convert 230 VAC to 30 VDC?

Answer 1

With a power supply that takes 230 vac and converts it into 48 vdc. Depending on power requirements, the typical power supply contains a transformer to step down to an appropriate lower voltage, a rectifier to convert to pulsating DC, a filter to smooth the ripples out, and a regulator to fine tune to output voltage. In higher power applications, there might be no transformer. Instead there is a rectifier to produce high voltage DC, followed up by a switching power charge pump, which is modulated by the regulator to produce varying duty cycle pulsating DC into a large inductor, producing the DC. The switching power supply is very efficient, minimizing losses across the regulator, at the cost of more complexity. Most, if not all, modern computer power supplies are of the switching type and, even though they are more complex, they are cheaper to build and operate.

Answer 2

use 230v to 12 v transformer after use rectifier circuit.

Answer 3

A: An easy way is to buy a transformer 230v to 50v and bridge rectify the output . There is power to be considered in any projects.

Answer 4

The 230 VAC has to be transformed down to 30 VAC and then rectified with a half or full wave diode bridge to change the voltage from AC to DC.

Answer 5

by step down transformer
