![]() This method is called freq modulation scheme.The chopping frequency has to be varied over a wide range for the control of voltage. In this scheme, either TON (or) TOFF is kept constant and the chopping period (T) is variable. this is realized in 2 different strategies ![]() It can be considered as dc equivalent to an ac transformer Process of converting ac into pulsating DC with the help of power semiconductor devices such as Diodes,SCR,transistors etc.Ĭhopper is a high speed static switch used to obtain variable dc voltage from a constant dc voltage.
