Abstract

This paper investigates the use of current sensors for control of power converters. The whole system only requires current sensing devices that generate signals in response to the current flowing in inductors. Besides, such as used in current programming and in maximum current protection, the sensed current and the rate of change of the inductor current in different circuit topologies are used to determine the input and output voltages. Apart from reducing the number of sensors, the proposed method provides inherent electrical isolation between the power conversion stage and the controller, and thus reducing noise coupling.
