Chopper can operate in any of the 4 quadrants by an appropriate arrangements.Ī device which converts input power at one frequency to out power at a different frequency with one stage conversion is called a cyclo converters.

chopper circuits are unidirectional devices.(ie) polarities of O/P voltage and the direction of current are restricted.

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.
