Ac voltage reduction method

[deepakchikane]

Dear techies,
could you pls let me know that,
can we regulate a ac voltage by clipping the ac waveforms..??

like input voltage is 260 voltage & i i clipped fired triac at 90degrees so it will give me rms value of 130 volt..

so like we can do it as a voltage stabiliser by clipping..

what will be efffects on end applications??
will the cliping ac waveforms leads to realibility of end application..

i am talking about higher voltage not lowered

this is just idea..

can anyone tell me about this..?

look forward to hearing you soon..

The method you are using is called phase control.

If you are using a resistive load, yes this will work.

For inductive loads, or loads with a rectifier-capacitor input, this doesn't work. Not at all.

The exception are small shaded-pole induction motors, like those used on table fans, on which you can control its speed by phase control.
