The Steady-State and Transient Characteristics of the Chopper-Modulated Circuit Having Four Circuit Modes

Abstract

The problem considered in this paper is one, in general, of making clear the characteristic of chopper-modulated circuits from the theoretical point of view. The chopper-modulated circuit under consideration is assumed to have four circuit modes. In a previous investigation, we have already discussed a chopper-modulated circuit having common two circuit modes, and also have developed the valuable analytical method for a periodically interrupted electric circuit having two circuit modes excited by a complex sinusoidal input. Here we shall generally extend the foregoing analytical method for a periodically interrupted electric circuit having m circuit modes driven by a complex sine wave input and basing on this method, we shall discuss a chopper-modulated circuit having four circuit modes. Only a type of practical interest is treated, that is, the transformer coupled chopper-modulated circuit which is frequently used with conventional chopper amplifiers, and other types which are not considered here. The method considered in this paper is an available technique explained to make clear the steady-state and transient performance of these types.
