Because you can't. The secondary voltage is caused by the change in current (di/dt) in the primary. Likewise, when current flows in the secondary, there is a "back electromagnetic force" that induces a voltage in primary that causes current to increase in the primary. This transformer action is determined by the change in current, and doesn't by nature change the frequency.
For every 1% increase in frequency, the core flux reduces by 1%. That means that at higher frequencies the transformer can be used at a higher voltage proportional to frequency - subject to the insulation strength.
The transformer works because the frequency of the AC source is what produces the varying magnetic field in the transformer core producing a voltage of the same frequency in the secondary.
The V/Hz ratio should be kept constant. If the frequency dips too much, the core will be saturated by the excessive voltage.

Why frequency is constant in a single phase transformer?
a transformer or inductor or capacitor does not change frequency frequency is controlled at the generating station with the speed of the motor or turbine the number of phases will not make a difference an inductor or capacitor can shift phase up to 90 degrees you can make 3 phase power from single phase power with inductors capacitors and transformers
Will a 110V 60Hz home theater system bought in the US work in Singapore which uses a 220V 50Hz by just using a voltage transformer?
Your stereo system has an internal transformer in the power supply that is designed to operate at a given frequency. If it is designed to operate at the load your stereo system will use at 50 Hz, then yes. Otherwise this transformer will overheat when connected at the wrong frequency, and will burn out. You might be lucky and the power supply may be labelled to operate at 50 or 60Hz; if not, I recommend contacting the manufacturer. A voltage transformer will convert 50Hz 220 to 50Hz 110. To change frequency, you need special equipment.
Can you use choose any frequency for current supply?
Yes you can as long as it is in the very low frequency band, below RF, up to 700 Hz. The higher the frequency the smaler the transformer for the same output power and smoothing is also easier.
How do you make a 380v motor run on 220v?
Yes just connect any line to neutral you have 230volts already.
What is the Frequency Supply in UAE?
Supply Frequency in UAE is 50Hz

How can you step down a 15kv transformer single phase to 220v?
A transformer steps the voltage of an electrical power supply up or down. The transformer must be correctly designed for the voltage and current levels that it is intended for. Only ac can be used with a transformer, which is designed to work at a particular frequency.

4 What is the difference between a transformer and a rectifier Which are found in a PC power supply?
A rectifier is a device that converts alternating current to direct current. A transformer is a device that changes the ratio fo current to voltage. A rectifier is found in a PC power supply.
How do you make a 380v motor run on 220v?
Yes just connect any line to neutral you have 230volts already.
What is the difference between a transformer and a rectifierwhich are found in a PC power supply?
The rectifier is what changes your AC into DC that the computer can use. Transformer raises or lowers the voltage. So you have 110 volts AC coming into your computers power supply. The Rectifier circuit in there changes the AC voltage to DC voltage but it is still to high for the computer use. The transformer lowers that voltage down to the various voltages that your computer needs
What is the difference between a transformer and a rectifier Which are found in a PC power supply?
A transformer is a device that changes the level of an a.c. voltage, while a rectifier is a device that converts alternating current to direct current.
What relationship exists between input and output of a transformer?
A transformer changes voltage, for more efficient transfer over long distances, or for less voltage from mains supply into a 130v Laptop or equivalent.
How many mutual flux in a transformer be maintained constant while varying both supply voltage and frequency?
Please rephrase your question so that it makes sense.
Why does a transformer only work for AC supply and not DC supply?
A transformer makes and collapses a magnetic Field inside 60 times a second for home power in North America, 50 times a second in Europe. The building and collapsing of a magnetic field "Induces" a voltage in another transformer winding. DC current only creates a stable magnetic field and this will not create or induce voltage in the other winding. Normally covered in grade 5 science where I live.
Single phase motor speed is determined by the?
frequency of the power supply it is connected to. The speed of a single phase motor is directly related to the frequency of the alternating current (AC) power supply. As the frequency of the power supply changes, the speed of the motor will also change.
