If the input is pulsating DC, then the output will be pulsating DC. It will not be shaped the same, but it will be close, depending on the frequency and rise and fall time in comparison with the inductive reactance of the transformer.

Is there a pulsating current dc transformer?
Yes, an example is an automobile's ignition coil, which is energised from the battery, via the contacts within the distributor. The contacts open and close, supplying the ignition coil with pulsating current.
Does electrical transformer use a DC or AC source?
A transformer is a device to convert high voltage AC to low voltage AC & vice-versa. It works on the principle of induction. Since induction occurs only in an AC supply, a transformer cannot work on DC.. So, it is not possible to convert DC supply to AC using transformer. You would need an inverter to convert DC to AC.
Can a transformer work using dc?
no. because if we use dc source for transformer there will be no production of energy for the secondary side since they are mutually conducted, as the transformer is a static device which can transmite the energy from one circuit to other with out changing the frequency and also there is no movement of the conductors. in order to produce the emf there should be either conductor movement or moving flux so the dc source will produce constant field flux hence there is no production of energy in the secondary side.
Why use capacitor in circuit?
To smooth the output of the pulsating DC.
How do you make a power supply?
It depends on what you want to use it for. Assuming you will be working with a 110 volt AC input and want a 9 or 12 volt DC power supply, you will need a transformer to reduce the AC voltage, then you will need a rectifier to convert it to pulsating DC (a full wave rectifier works better than a half wave rectifier) and a capacitor to smooth out the pulses. Some devices like solenoids and valve actiuators work well with pulsating DC but some applications demand pure DC. That is the basic design of most power supplies. You may need to regulate the voltage which is required in some applications.
Does transformer works on DC?
I should think not
What does filter do in a transformer?
A transformer does not use a filter. You may be asking about the use of a filter in a power supply. A power supply uses a filter to change pulsating DC from the rectifier into smooth DC for the circuits that the power supply powers.
Why diodes are used after center tapped transformer in dc to ac inverter?
Diodes are used after a center-tapped transformer in a DC to AC inverter to rectify the alternating current (AC) output of the transformer into pulsating direct current (DC). This rectified voltage is then smoothed using filters to produce a more stable DC waveform. The diodes act as one-way valves, allowing current to flow in only one direction, thus converting the AC voltage into a pulsating DC voltage.
Is there a pulsating current dc transformer?
Yes, an example is an automobile's ignition coil, which is energised from the battery, via the contacts within the distributor. The contacts open and close, supplying the ignition coil with pulsating current.
Which type of transformer is used in mobile charger?
The transformer used in mobile is pulse transformer which operates at very high frequency pulsating DC in order to make charger energy efficient and light weight.
Why transformer do not operate with DC?
Transformer works with varying flux. DC won't create it. Only AC produce varying flux.
What is the pulsating DC frequency?
When AC full wave is rectified into DC by using bridge rectifier .The DC do not actually behave like an ordinary DC and the DC has a constant value .In fact, it is in pulsating form.This is known as Pulsating DC.
Why transformer is connected to ac?
Because of how a transformer works. Basically a transformer have a primary and a secondary winding sitting close to each other, with the primary connected to the ac source. Pushing ac through the primary wionding creates a pulsating magnetic field. Pushing a pulsating magnetic field through the secondary winding creates an electric current in it. That current will also be ac, but dependent on the number of turns in the windings it will have another voltage. DC don't give a pulsating magnetic field from the primary winding, and a stationary magnetic field won't generate any electricity in the secondary winding.
Why transformer works on ac not dc give two reasons?
A transformer requires a changing input to generate an output.
Do transformers work on DC supply?
No, unless you have a pulsating DC
Is welding transformer a frequency changing transformer?
Not really. Frequency in is frequency out, unless there is some conversion circuit in between, such as a motor-generator set or some kind of inverter. You may (and should) notice, however, that a typical welding transformer is rectifying three phase AC to DC, using a full wave rectifier. This results in a pulsating DC voltage where the ripple frequency is 360hz.
What component of a motor changes induced AC voltage into a pulsating DC?
its commutator..which converts ac produced by and motor to pulsating dc ... more the commutator divide more accurate dc..means less pulse in dc
