Multiloop controller design for a quadratic boost converter
Electric exciters; Feedback; Networks (circuits); Optimization; Parameter estimation; Power converters; Closed loop response; Fourth order dynamics; Quadratic boost converter; Single switch; Electric control equipment
A controller design methodology is given for a quadratic boost converter with a single switch using current-programmed control. Nonlinear and linear models are developed, the later exhibits fourth-order characteristic dynamics with complex right-half plane zeros. The proposed control scheme is based on sensing the current of the switch and using it for feedback purposes. When the current loop is introduced, the fourth-order dynamics of the converter are changed to a dominant first order, which simplifies substantially the controller design of the outer loop. For this loop, a conventional controller is designed. The design-oriented analytic results allow the designer to easily pinpoint the control circuit parameters that optimise the converter%27s performance. At the end, experimental results are given for a 23W quadratic boost converter where open loop and closed-loop response are compared. © The Institution of Engineering and Technology 2007.
