A)PDF, 298 Kb, Revisión: A, Archivo publicado: sept 15, 2010
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. - Create an Inverting Power Supply from a Step-Down Regulator (Rev.
