One of the well-known benefits of current-mode control is that the system stability can be easily achieved by Type II compensation design. It is possible to improve the transient response of a current mode DC/DC converter by adopting Type III compensation to boost the crossover frequency and phase margin. Type III compensation is simple to design and needs only one extra component. - Intel VR11.1 Server Reference DesignPDF, 38 Kb, Archivo publicado: jul 21, 2010
