base voltage given to transister is suffecient to turn on it , even though it is not in saturation, once it become on due to +ve feedback winding it will take to saturation.when core become saturate ur feed back winding vtg also become 0, but still to make transister fully off some -ve vtg is required to apply to base , how this vtg will induce to feedback winding
when the inductor W1 saturates it means that all the energy is stored in the form of magnetic energy and this means no current or very less current which is not enough to drive the transistor and hence the transistor turns off...
when the transistor turns off the other inductor W2 magnetic field collapses which makes W1 magnetic field collapsing which results in current drive to the transistor which then turns it on and after sometime saturation occurs and transistor turns off... this continues....
dude the inductor is a reactive component and once it starts saturating the current through it starts dropping... for a inductor V=L(di/dt) and hence when the current starts reducing di/dt becomes negative and the voltage across the inductor starts becoming negative.... so the transistor turns off...
Dear Sir, Can somebody help with a Class D high
power Circuit Digram About 1000 Watts into 8 omhs
as I like to build one to use in my Band,I really cant
afford to buy one. Thanking You.
