Abstract :
In this paper, the averaged model and linear control of a 2D KY buck-boost converter are developed. Unlike the traditional buck-boost converters, the KY converter has fast transient response, similar to the behavior of the buck converter with synchronous rectification. In addition, it has a non-pulsating output current. The KY converter operates in the Continuous Current Mode (CCM) which, not only reduces the stress on the output capacitor, but also reduces the ripple of the output voltage. Simulation results are provided to demonstrate the effectiveness of the proposed control system.
