Boost converters have nonlinear characteristics by semiconductor switching elements in a circuit. Generally, controllers are designed by a linearized model of the boost converter based on state space averaging method. This study proposes design scheme considering discontinuous conduction mode without linearization. In detail, firstly, modeling of boost converter in discontinuous conduction mode is...
This paper proposes a digital control system applied to a power factor correction boost converter rated to a wide range of output power, operating in mixed conduction mode with fixed switching frequency. The control system is composed of an input current controller and an output voltage controller. The current controller comprises two predictive model-based control laws (one for the continuous conduction...
A novel control technique for the control of switching DC-DC converter, multilevel pulse train (MPT), is proposed and studied in this paper. MPT control scheme is simple and easy to design, with great control performance. Boost converter operating in discontinuous conduction mode (DCM) is taken as an example to study the operation principle, voltage ripple analysis and control pulse combination analysis...
