A new current programming technique using predictive control

This paper investigates a new current programming technique for constant frequency switch-mode power converters. In the proposed technique, the duty cycle of the power converter switch is controlled by the input and output voltage as well as inductor current information. The basic idea in predictive control is to force the inductor current to follow the command current within one switch cycle. This new technique removes several drawbacks of conventional current mode control, such as current loop instability and error between inductor peak current and command current. The boost power converter is used as an example of the implementation of this new technique.<
