Compensating The RHPZ In The CCM Boost Converter: Using A Simulator

In the previous article (See Power Electronics Technology, June 2009), we showed how to compensate the boost converter operated in continuous conduction mode (CCM) using an analytical approach. Despite its repulsive aspect, the analytical study is extremely important for the design phase as it unveils the dependency of the poles and zeros locations with varying parasitic elements. It is, therefore, the designer’s duty to ensure that the impact of these parasitic elements is well under control, and in keeping with the right design margins despite unavoidable production dispersions.
