For linear supplies, the straightforward answer is: THE VOLTAGE GOES DOWN.
For regulated unipolar switching supplies (all bets are off), it is likely that your pulse width will increase until you are at the regulated voltage set at the chip. Not all DC supplies behave the same way.

Difference between input and output transformer?
The 'input' side of a transformer is called its 'primary' side, whereas the 'output' side is termed its 'secondary' side. The ratio of its secondary to primary voltage is equal to the ratio of the number of turns in the secondary windings to the number of turns in the primary winding. So if, for example, a transformer's secondary winding has twice as many turns as its primary winding, then the secondary winding will produce twice the voltage applied to the primary winding.
What happens to voltage in a step-down transformer?
The voltage induced into the secondary winding will be lower than the voltage applied to the primary winding. The primary winding being the winding connected to the supply, while the secondary winding is the one connected to the load.
In a transformer primary or secondary will inside winding?
A step-down transformer's primary is high voltage and secondary is low voltage, based on voltage configuration or load we select which winding we do fast.In air-cooled Transformers output voltage is high and load current is low. So in air cooled low voltage winding in side and high voltage winding in out side of the coil . So we can reduce high voltage short problems and we can easily provide coil insulation . reduce short problem. It is cooled in oil.In step-down transformers we can do high voltage inside of the coil and low voltage and high current of the coil is outside. Because we can better coled in outer side . and reduced to temp problems.AnswerThe terms 'primary' and 'secondary' do not relate to a transformer's voltages, but to how its windings are connected. The primary winding is connected to the supply and the secondary winding is connected to the load. So, for a step-up transformer, the secondary winding is the higher-voltage winding while, for a step-down transformer, the secondary winding is the lower-voltage winding. Your question, therefore, should ask whether the higher- or the lower-voltage winding is the 'inside' winding (i.e. the winding closest to the core), and the answer is that it is the lower-voltage windings are innermost and the higher-voltage windings that are outermost.
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.
What is considered to be the primary side on a step down transformer?
Transformers have windings - typically each winding is designated for a particular voltage. Any one of the windings can be an "output", as any winding can be an "input". Usually for consumers, one of the windings is intended to be 120V for the input. In that case, all of the other windings would be an output.I should also mention that while you can have several outputs, you can only have one input. Some transformers have the windings color coded to designate input and outputs.Hope this helps!
How the input voltage is changed to an output voltage in a transformer?
Transformers work on the induction principal of the flux of the primary winding cutting the wires of the secondary winding. The amount of turns in the primary in relationship to the amount of turns in the secondary is the transformers winding ratio. This ratio is what governs the voltage value of the secondary winding.
Difference between input and output transformer?
The 'input' side of a transformer is called its 'primary' side, whereas the 'output' side is termed its 'secondary' side. The ratio of its secondary to primary voltage is equal to the ratio of the number of turns in the secondary windings to the number of turns in the primary winding. So if, for example, a transformer's secondary winding has twice as many turns as its primary winding, then the secondary winding will produce twice the voltage applied to the primary winding.
Does a weak battery voltage affect the voltage output of the ignition coil?
Ignition Coil Output Voltage versus a Weak BatteryYes, an ignition coil is nothing more than a dedicated, specialized transformer. As such, the lower the voltage in the primary winding, then the lower the voltage induced in the secondary [output] winding.
If the primary winding of the transformer in the power supply opens what will you observe in the rectified output?
There would be no rectified output. The transformer primary has to be closed to induce a current into the secondary winding. At this point of the secondary the voltage is still AC. This voltage is then applied to the rectification bridge to change it to DC. So you can see how no voltage on the primary, the same as the unit being unplugged, affects the output voltage.
When will transformer voltage be zero?
A transformer output voltage will be zero when A. The input voltage is zero. B. When the primary (input) wire winding inside the transformer is broken, cut, or burnt out. C. When the secondary (output) wire winding is broken, cut, or burnt out.
What is the point of a step up transformer?
A 'step-up' transformer is a transformer with more turns on its secondary winding than on its primary winding. It's secondary (output) voltage is, therefore, higher than its primary (input) voltage.
What happens to voltage in a step-down transformer?
The voltage induced into the secondary winding will be lower than the voltage applied to the primary winding. The primary winding being the winding connected to the supply, while the secondary winding is the one connected to the load.

How do you measure the power input and power output for the step-up transformer?
Power input to a transformer = (voltage across the primary winding) x (current through the primary)Power output = (voltage across the secondary winding) x (current through the secondary)It doesn't matter whether the transformer is used in step-up, step-down or simple isolation.
What are the output voltage and current of a transformer determined by?
The secondary (output) voltage is determined by the primary voltage and the turns ratio of the transformer. The secondary current is determined by the secondary voltage and the load resistance.
