infact we get better efficiency using high freq , what are the diadvtanges

Most of the appliances/electronic equipment won't work.
Actually, in US 110 V - 60 Hz is used whereas in India 230 V - 50 HZ is used. If we take some electronic equipment from India to US not only we are required to convert the voltage but freq as well.

Motors and transformers are designed to work at a specific frequency. THey would not work with that higher frequency (like if you used an aircraft's 400 Hz generator).
Light bulbs would not care. In fact electronic ballasts for fluorescents use the line voltage and frequency to drive an oscillator in the 20000-40000 Hz range so they can use a smaller cheaper transformer internally.

2 things can happen
1. You either blow the power supply unit if you have a large amount of feedback form inductive devices(motors)
2. You blow the appliance due to overheating mainly. (motors may over rev
Unless you are talking of a resistive load such a a boiler heater or a bulb, whereas the amount of work produced will depend on the frequency of the source.

you may be fairly youthful to hearken to it. in any case, that doesnt sound prevalent. nicely, no longer for mine in any case. It doesnt make any noise and its kinda old. also, i'm in person-friendly words 16 so i visit nonetheless listen those extreme pitch sounds. for this reason, i visit properly state that it doesnt make any noises like that. Yours should be going out. you should the contact the organisation that makes it.
