To change from 120 V AC to 24 V AC, just connect it up to an appropriate transformer. To convert 120 V AC to 24 V DC, you'd need a transformer followed by a full-wave rectifier and filter capacitors.

A: The easier way is to step down with a transformer to 30 volts AC rectify it and add a regulator like LM117 to get to 24volts then add a second LM117 to get to 12 volts. Now both are good up to one amp. Th other way is to design PDM and get both voltages. This will be simpler and less bulky but not easy to implement for a guy that ask this question

It is not in any way equivalent. Wrong terminology in the question?

You will need to find a inverter, or you can use a DC motor coupled to a AC generator.

Use a step down transformer (220 VAC to 24 VAC) and then use a rectifier of suitable rating and type to convert 24 VAC to 24 VDC.

Why does amplifier gain reduce?

Since we know that the amplifier gain is given by A=Output voltage/input voltage (where A is the amplifier gain) So, it can be written as output voltage=A*input voltage, so when the output part increases gain increases but when input part increases gain decreases

How does a stabilizer?

A home voltage stabilizer reduces (buck) or increases (boost) the out put voltage for respective increase and decrease in line voltage. To reduce output voltage the relay cutoff some transformer winding turns, and to increase output voltage the relay add some transformer winding turns in predefined steps.

What is the difference between a step down chopper and a buck converter?

Choppers are dc - dc converters, on the basis of output voltage level step down chopper is used for output voltage less than input one. A buck converter is a step down chopper with a LC filter at the output end in order to reduce the voltage ripples.


Why do a Voltage transformer give me a CLIPPED output signal?

Because the voltage on the primary winding is too high and the core gets saturated. When this happens the transformer effect cannot kep increasing the voltage on the secondary winding, clipping the output. Either reduce the voltage on the primary of get a oriented iron core with at least 10,000 gauss flux capacity.


How do you reduce a ripple voltage?

You reduce ripple voltage by adding a low-pass filter. In the simplest case, you put a capacitor after the rectifier. The peak voltage will be the rectifier output voltage less the forward bias of the rectifier, while the minimum voltage will depend on current and capacitance. In a more complex case, you could use an LC filter, making the peak voltage smaller. Specifics are dependent on the power and performance requirements.


What is the working of the regulator?

n electrical regulator by using resistance the output voltage is varied simultaneously the speed is varied... But to reduce the the energy loses in the resistor, electronic regulator is introduced,which uses triac to vary the output voltage by varying the firing angle.Which avoids lose of energy in resistor...


How do you increase voltage?

You can put less resistance (more load) on the battery with larger wires, but if you exceed a particular current output for a given duration, you will overheat the battery. To safely increase current output, use two batteries connected in parallel.


Is low voltage harmful to electronics?

No the low voltage is not harmful for all ever . if you applied low voltage than the output power of your device will low and you can also observe that the performance of your device will also reduce. it may also make the device inactive.


What is ripple voltage in 12 volt power supply?

A: Ripple is a residual voltage evident as voltage following the AC input frequency. The ripple magnitude is a function of not enough of both filtering capacitance or overloading the output. Increasing capacitance will reduce the ripple or reducing the loading
