Analytical & State-Space Control Methodology

After reviewing the operation of an ACF power stage, it introduces the ACF transfer function, shows Bode plots for a design example based on the NCP1566 active-clamp PWM controller and discusses selection of the crossover frequency. The impact of the pulse-width modulator (PWM) on the transfer function is also explained, along with a technique for accounting for the PWM. The design of a type-3 compensator, as well as a strategy for applying this compensator to the ACF, is described and demonstrated using a Simplis simulation. All of this leads to the presentation of a complete circuit for the design example and its key features, circuit elements and additional design considerations are discussed. Finally, a common technique for making the Bode plot measurements of the loop’s gain and phase margins is reviewed and the benefits of using a low-cost oscilloscope and frequency response analyzer (Cleverscope) to make these measurements are highlighted. What you’ll learn: How to compensate an active-clamp forward converter operating in voltage-mode control How to define the transfer function of an active-clamp forward converter How to understand the benefits of making Bode plot measurements using the Cleverscope frequency response analyzer View the Source Author & Publication: Christophe Basso, ON Semiconductor, Toulouse, France, How2Power Today, Jun 17 2019 This article describes in detail how to compensate an ACF.
